[0001] The present disclosure relates to a field of foundation monitoring. More specifically, the present disclosure relates to a method for predicting and monitoring structural integrity of concrete foundation.
BACKGROUND
[0002] A concrete foundation acts as a base on which architectural structure is build. The architectural structure is any structure such as transmission tower, mall, building and the like. The construction of concrete foundation requires quality check in order to get the desired strength for holding the architectural structure. The quality check of the concrete foundation is done based on human inputs which include visual inspection. The quality inspector performs visual inspection of the concrete foundation on the day of construction. In addition, the inspector has to visit each location for the inspection of all the concrete foundation which is being constructed for the transmission tower. Further, the inspector has to visit all the concrete foundation gain for the inspection after every specified period of time. The concrete foundation for the transmission tower is constructed in the outskirts which need to be visited for the inspection. The inspection done by the quality inspector involves only the visual inspection of the concrete foundation which is time consuming. The inspection performed does not involve the technical parameters for the concrete foundation to find out the strength gain by the concrete foundation.

The user 102 is having knowledge of strength required by the concrete foundation 106 and standards which need to be followed for the concrete foundation 106.
[0017] The concrete foundation 106 is the structure or base on which architectural structure is assembled. The concrete foundation 106 of the architectural structure plays an important role in safety and satisfactory performance of the architectural structure. The strength of the concrete foundation 106 is required to bear load of the architectural structure. The concrete foundation 106 requires continuous monitoring to check that the concrete foundation 106 is strong enough to bear load. The term load here refers to total weight on the concrete foundation. The concrete foundation 106 is considered to be either shallow or deep which depends on the strength required for holding the loads. Also, the concrete foundation 106 is the lowest supporting layer of the architectural structure. The concrete foundation 106 is made from concrete. The term structural integrity refers to health and condition of the concrete foundation 106.
[0018] The use of concrete for the concrete foundation 106 depends on the strength required for the architectural structure. The concrete foundation 106 is made below the ground to get required strength for the architectural structure. The land is

excavated in proper shape to a suitable depth for the concrete foundation 106. The land is excavated by the user 102.

Further, the desired structure being of rectangular shape which consists of iron bars to provide strength. Furthermore, the concrete is prepared for getting the desired strength for the concrete foundation 106. [0019] In general, the concrete is a composite material composed of coarse aggregate bonded together with fluid cement that hardens over time. The fluid cement acts as a binder, a substance used for construction that sets, hardens and adheres to other materials, binding them together. In an embodiment of the present disclosure, concrete mix design is required to achieve target strength in structures. In another embodiment of the present disclosure, the concrete includes but may not be limited to mix design of M20, M25 and M30 grade of concrete for the concrete foundation 106. In another embodiment of the present disclosure, the concrete foundation 106 uses M25 and lower grades of concrete for making the concrete foundation 106. [0020] The concrete is poured into the desired structure or excavated land to make the concrete foundation 106 and curing is done in order to get desired strength of the concrete foundation 106. In general, the term curing is maintaining of an adequate moisture content and temperature in concrete to develop properties the concrete foundation 106 is designed to achieve. In addition, curing is the process for monitoring concrete foundation 106 to get the desired strength of the concrete foundation 106. The term curing refers to a process during which a chemical reaction or physical action takes place, resulting in a harder, tougher or more stable linkage. Further, the concrete maturity sensor 110 and the strain gauge sensor 112 are embedded inside the concrete foundation 106. The concrete maturity sensor 110 and the strain gauge sensor 112 are connected with wire procuring outside the concrete

foundation 106 to make connection to the data logger 114. In an embodiment of the present disclosure, the connection between the data logger 114 and the concrete maturity sensor 110 is a wireless connection, wired connection and the like. In an embodiment of the present disclosure, the connection between the data logger 114 and the strain gauge sensor 112 is a wireless connection, wired connection and the like.
[0021] The concrete maturity sensor 110 is a short term sensor. The concrete maturity sensor 110 senses temperature of the concrete foundation 106 on periodic basis.

In an embodiment of the present disclosure, the number of the concrete maturity sensor 110 embedded inside the concrete foundation 106 may be of any number required for monitoring the concrete foundation 106. The concrete maturity sensor 110 is activated when the pulse from the data logger 114 activates the concrete maturity sensor 110 to read the temperature of the concrete foundation 106. In an embodiment of the present disclosure, the concrete maturity sensor 110 is activated before it is kept inside the concrete foundation 106. In another embodiment of the present disclosure, the concrete maturity sensor 110 is always in the activated mode to read the temperature of the concrete foundation 106. In an embodiment of the present disclosure, the concrete maturity sensor 110 consists of memory for storing the data on periodic basis.
[0022] The strain gauge sensor 112 is a long term sensor. The strain gauge sensor 112 senses the load or stress on the concrete foundation 106 on the periodic basis. In an embodiment of the present disclosure, the periodic basis include but may not be limited to 30 minute, 1 hour, 2 hour and 1 day. In an embodiment of the present disclosure, the number of the strain gauge sensor 112 may be more than one. The load or stress is the amount of weight the concrete foundation 106 is bearing at a particular instance of time. In an embodiment of the present disclosure, the strain

gauge sensor 112 collects the amount of stress on the concrete foundation 106. The strain gauge sensor 112 is activated when the pulse from the data logger 114 activates the strain gauge sensor 112 to read the stress on the concrete foundation 106. In an embodiment of the present disclosure, the strain gauge sensor 112 is activated before it is kept inside the concrete foundation 106.

In an embodiment of the present disclosure, the strain gauge sensor 112 consists of memory for storing the data on the periodic basis.
[0023] The data logger 114 is used for recording data on periodic basis. In general, the data logger 114 is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. In an embodiment of the present disclosure, the periodic basis include but may not be limited to 30 minute, 1 hour, 2 hour and 1 day. The data logger 114 records data corresponding to time at which the pulse was sent for recording the data. The data logger 114 sends a pulse to the concrete maturity sensor 110 and the strain gauge sensor 112 on the periodic basic for taking reading at a particular instance of time. The data logger 114 comprises of memory and battery. The memory of the data logger 114 is used for storing the data which is collected from the concrete maturity sensor 110 and the strain gauge sensor 112. The data logger 114 receives data in the form of pulses which is received back at the data logger 114. The data logger 114 is connected to the concrete maturity sensor 110 and the strain gauge sensor 112. The data logger 114 is placed above the surface near the site of the concrete foundation 106. In an embodiment of the present disclosure, the data logger 114 may be placed at any suitable places. The data logger 114 is connected with a wired connection to the concrete maturity sensor 110 and the strain gauge sensor 112 embedded inside the concrete foundation 106. The data logger 114 records data in inbuilt memory of the data logger 114.

[0024] The data logger 114 displays data in form of visual and non-visual representation. In an embodiment of the present disclosure, the visual and non-visual representation includes numerical figure, graphs, plots and the like. The data logger 114 records data in inbuilt memory of the data logger 114. The data logger 114 sends pulses on periodic basis. In an embodiment of the present disclosure, the data logger 114 is programmed to record pulses of data after specified interval of time. The specified interval of time is specified by the user 102. In another embodiment of the present disclosure, the data about the concrete foundation 106 is erased from memory of the data logger 114. The data logger 114 sends data to a server 206. Also, the data may be manually fetched by the user 102. The data logger 114 again starts recording data about the concrete foundation 106.
[0025] Further, after the concrete has been poured into the concrete foundation 106 it is left for the hardening or setting. After the concrete has been poured, the user 102 inspects the concrete foundation 106 to check if the standards have been maintained for the installation of the concrete foundation 106. The user 102 inspects the concrete foundation 106 with the image capturing device 104. The image capturing device 104 is any device which has a camera embedded inside the image capturing device 104. In an embodiment of the present disclosure, the image capturing device 104 is an unmanned aerial device which is used to capture real time image of the concrete foundation 106. The image capturing device 104 is used to capture one or more images of the concrete foundation 106 at different angles. The one or more images of the concrete foundation 106 are having time-stamp and geo-tag attached to it. In an embodiment of the present disclosure, the one or more images are stored in the image capturing device 104. In another embodiment of the present disclosure, the one or more images are sent to the server 206. In general, geo-tag is addition of geographical identification metadata to a plurality of media. The plurality of media includes but may not be limited to geo-tag photograph, geo-tag video, geo-tag website, geo-tag SMS messages and the QR Codes. The data usually includes

latitude and longitude coordinates. The data includes but may not be limited to altitude, bearing, distance, accuracy data, place names and time stamp. [0026] In an embodiment of the present disclosure, the user 102 inspects the concrete foundation 106 from a remote location with the image capturing device 104 installed 5 at the concrete foundation 106. In an embodiment of the present disclosure, the image capturing device 104 is pre-installed at the geo-location of the concrete foundation 106. In another embodiment of the present disclosure, the image capturing device 104 is installed around the concrete foundation 106 at various sides. In an embodiment of the present disclosure, the image capturing device 104 is fixed
10 to the surface. The surface itself may be stationary or fixed. Also, the user 102 need not carry the image capturing device 104 every day to capture images of the concrete foundation 106. In another embodiment of the present disclosure, the image capturing device 104 is the unmanned aerial device which captures real time images of the concrete foundation 106 from air. In another embodiment of the present
15 disclosure, the image capturing device 104 is timed at periodic intervals to capture and send images of the concrete foundation 106.
[0027] The one or more images captured by the image capturing device 104 are being analyzed by the user 102 to perform visual inspection of the concrete foundation 106. In an embodiment of the present disclosure, the one or more images captured by the
20 image capturing device 104 are analyzed by using machine learning algorithm. In an embodiment of the present disclosure, the one or more images captured by the image capturing device 104 are analyzed to identify deviation from the standard process for the concrete foundation 106. [0028] In an embodiment of the present disclosure, the image capturing device 104
25 captures the one more images having geo-tag information. In addition, the geo-tag information is utilized to verify whether the specifications for the construction of the concrete foundation 106 are followed or not. Also, the one or more images with geo-tag information verify that there is no mismatch about the location data of a plurality
11

of the concrete foundation 106. The capturing of images with geo-tag and time-stamp provide a higher grade of accuracy for the categorization of the one or more images. The one or more images are inspected by the user 102 for checking construction of the concrete foundation 106. 5 [0029] Further, after the analysis of the one or more images required changes are made in order to get the desired strength of the concrete foundation 106. In addition, the concrete foundation 106 is left for the setting and the reading is taken by the data logger 114 periodically. In an embodiment of the present disclosure, the time interval for sending the pulse and take recoding from the concrete maturity sensor 110 and the
10 strain gauge sensor 112 is pre-defined by the user 102. In another embodiment of the present disclosure, the time interval for sending the pulse and take recording from the concrete maturity sensor 110 and the strain gauge sensor 112 is set to default time interval automatically. [0030] Furthermore, after a first pre-defined time interval the ultrasonic tester 108 is
15 used for monitoring structural integrity of the concrete foundation 106. In an embodiment of the present disclosure, the first pre-defined time interval is less than 07 days from initial day of pouring concrete into the concrete foundation 106. The ultrasonic tester 108 is used to measure a first strength of the concrete foundation 106 before backfilling by sending ultrasonic waves in the concrete foundation 106. The
20 ultrasonic tester 108 provides ultrasonic pulse velocity testing for the concrete foundation 106. The ultrasonic tester 108 is kept on the surface of the concrete foundation 106 to get reading of the concrete foundation 106. In an embodiment of the present disclosure, the ultrasonic tester 108 takes reading from surface of the concrete foundation 106 by placing the ultrasonic tester 108 at different places on the
25 concrete foundation 106.
[0031] Reference will now be made to FIG. 2 for various embodiment of the present disclosure for predicting and monitoring structural integrity of the concrete foundation 106. It may be noted that to explain the system elements of FIG. 2,
12

references will now be made to the elements of FIG. 1. The interactive computing environment 200 includes the ultrasonic tester 108, the concrete maturity sensor 110, the strain gauge sensor 112, the data logger 114, a communication network 202 and a foundation monitoring system 204. Further, the interactive computing environment 5 200 includes the server 206 and a database 208.
[0032] The interactive computing environment 200 includes the communication network 202 for communicating information. The communication of information is between the foundation monitoring system 204 with the concrete maturity sensor 110 and the strain gauge sensor 112. In an embodiment of the present disclosure, the
10 communication network 202 enables the foundation monitoring system 204 to gain access to the internet. Moreover, the communication network 202 provides a medium to transfer the data between the foundation monitoring system 204 with the concrete maturity sensor 110 and the strain gauge sensor 112. Further, the medium for communication may be internet, infrared, microwave, radio frequency (RF) and the
15 like.
[0033] Further, the interactive computing environment 200 includes the foundation monitoring system 204 for predicting structural integrity of the concrete foundation 106 in real time. Furthermore, the foundation monitoring system 204 monitors structural integrity of the concrete foundation 106. The foundation monitoring
20 system 204 is connected to the ultrasonic tester 108 and the data logger 114. In an embodiment of the present disclosure, the ultrasonic tester 108 and the strain gauge sensor 112 are connected to the foundation monitoring system 204 through a wireless or wired connection. [0034] The foundation monitoring system 204 measures the first strength of the
25 concrete foundation 106 before backfilling. The first strength of the concrete foundation 106 is measured by the ultrasonic tester 108. The first strength of the concrete foundation 106 is measured in real time. The ultrasonic tester 108 is placed on the surface of the concrete foundation 106. The first strength of the concrete
13

foundation 106 is measured at the first predefined time interval. The first predefined time interval is less than 07 days. The first strength of the concrete foundation 106 is associated with strength and foundation maturity achieved by the concrete foundation 106. Further, strength of the concrete foundation 106 refers to compressive strength 5 of the concrete foundation 106. In general, compressive strength of any material is defined as resistance to failure under the action of compressive forces. The compressive strength is an important parameter to determine performance of the material during service conditions. In addition, the foundation maturity refers to the setting or hardening of concrete maturity of the concrete foundation 106. The
10 concrete maturity indicates how far curing has progressed.
[0035] In an example, if M25 and M30 grade of concrete is used for the concrete foundation 106. After completion of the first pre-defined interval of time of less than 7 days, the ultrasonic tester 108 is used and the first strength of the concrete foundation 106 is measured.
15 [0036] Also, the foundation monitoring system 204 measures a first heat of hydration of the concrete foundation 106 for at least 30 days and beyond 30 days. The first heat of hydration is measured by the concrete maturity sensor 110. The concrete maturity sensor 110 is embedded inside the concrete foundation 106. The first heat of hydration is measured at a second predefined time interval. The second predefined
20 time interval is of 28-30 days. However, the second predefined time interval might not limit to the specified value.
[0037] Further, the first heat of hydration is collected from the data logger 114 associated with the concrete maturity sensor 110 which collect data on periodic basis by sending the pulse to the concrete maturity sensor 110. The pulse activates the
25 concrete maturity sensor 110 to sense the temperature or heat of the concrete foundation 106. The concrete maturity sensor 110 collects data on a periodic basis which is stored into the data logger 114.
14

[0038] The foundation monitoring system 204 generates a heat of hydration curve (as shown in FIG.3) in real time using the first heat of hydration after the second predefined interval of time. The first heat of hydration is collected from the data logger 114 associated with the concrete maturity sensor 110. The heat of hydration 5 curve (as shown in FIG.3) is a curve which is plotted based on the time and the temperature recorded by the data logger 114. Deviation from the heat of hydration curve shows that the concrete foundation 106 is showing the deviation from the desired properties for which it is constructed. [0039] In general, heat is liberated when cement is mixed with water. The heat
10 liberated due to hydration of cement is termed as heat of hydration. The hydration of cement refers to addition of water to cement to make the concrete which is poured in the concrete foundation 106. In general, the heat of hydration curve (as shown in FIG.3) of the cement is divided into four stages. The first stage is quick which lasts for a short interval of time. The first stage is quick due to rapid formation of an
15 amorphous layer of hydration product around cement particles. The formation of the amorphous layer prevents further dissolution of the cement particles. The first stage is followed by the second stage. The second stage is called as induction period in which no reaction occurs. [0040] Further, the heat of hydration curve (as shown in FIG.3) is followed by the
20 third stage. The third stage is called as rapid reaction period. The rate of reaction increases rapidly during the third stage. The rate of reaction reaches a maximum at a time period which is less than 24 hours after initial mixing. Further, the rate of reaction decreases rapidly to less than half of the maximum value. The reaction shows such behaviour due to hydration of C3S particles present in the cement. The
25 rate of hydration is controlled by rate at which hydration produces nucleate and grow. Also, the rate of reaction and time at which reaction occurs depend strongly on temperature and average particle size of cement. In addition, the end of the third
15

stage denotes up to 30% of hydration of cement and the concrete foundation 106 has undergone initial and final set.
[0041] Furthermore, the third stage is characterized with a continuous and rapid deposition of hydration products into a capillary porosity. The capillary porosity is 5 space which is initially occupied with mix water. The continuous and rapid deposition of hydration products causes a large decrease in the total pore volume and a concurrent increase in strength. Here, the hydration products primarily refer to calcium silicate hydrate gel and calcium hydroxide. [0042] The third stage is followed with the fourth stage. The fourth stage is termed
10 as diffusion-limited reaction period. In this period the dissolved ions from the cement are diffused outwards and precipitated into the capillary pores or water is diffused inwards to reach the left cement core which has not been reacted. [0043] Further, the concrete foundation 106 is backfilled with sand after the second pre-defined time interval. In general, backfilling is the process of putting soil back
15 around and above the concrete foundation 106. After the back filling and the required strength has been achieved on the first pre-defined time interval, assembling of a transmission tower is done on to the concrete foundation 106. In general, the transmission tower is a tall structure, usually a steel lattice tower, used to support an overhead power line. In addition, the transmission tower carries heavy transmission
20 conductor at sufficient safe height from the ground. The transmission tower is installed by following a process of first making the concrete foundation 106, after curing of the concrete foundation 106 the transmission tower is assembled and erected. Further, after an interval of time stringing is done for conductor and insulator. At each step, load is added to the concrete foundation 106 which should be
25 less than the strength achieved by the concrete foundation 106. Stringing is the mounting of the conductor and insulator on the transmission tower. The mounting is done from one transmission tower to the other transmission tower. Further, after the
16

second pre-defined time interval data is collected from the data logger 114 connected with the concrete maturity sensor 110.
[0044] Furthermore, the foundation monitoring system 204 measures a first load on the concrete foundation 106 for a period of at least 12-24 months. The load on the 5 concrete foundation 106 is measured by the strain gauge sensor 112 embedded inside the concrete foundation 106. The first load is measured at a third predefined time interval. The third pre-defined time interval is of 1 year. In an embodiment of the present disclosure, the third pre-defined time interval includes but is not limited to 1 month, 6 months, 1 year and 2 years.
10 [0045] Also, the first load on the concrete foundation 106 is collected from the data logger 114 associated with the strain gauge sensor 112 embedded inside the concrete foundation 106. The strain gauge sensor 112 collects data associated with the first load on the concrete foundation 106 on periodic basis. The strain gauge sensor 112 records the load which is applied on the concrete foundation 106 during assembly of
15 transmission tower and after stringing of the conductors.
[0046] In an example, the first load on the concrete foundation 106 is X, Y and Z. X refers to initial load on the concrete foundation 106. X is load on the concrete foundation 106 when the concrete foundation 106 is formed. Y refers to load of the transmission tower on the concrete foundation 106. Y is load on the concrete
20 foundation 106 when the transmission tower 116 is assembled on the concrete foundation 106. Z refers to load by the stringing of conductors and insulators on the concrete foundation 106. Z is load of wires that are connected on the transmission tower. In general, the transmission tower is stringed with wires to conduct electric power through the transmission tower 116. The stringing adds load to the
25 transmission tower which adds load on the concrete foundation 106. The strain gauge sensor 112 measures complete load on the concrete foundation 106 as the sum of all three variables. The total load on the concrete foundation 106 is the summation of the weight X, weight Y and weight Z.
17

[0047] Moreover, the foundation monitoring system 204 sends the first strength of the concrete foundation 106, the first heat of hydration of the concrete foundation 106 and the first load on the concrete foundation 106 to the foundation monitoring system 204 before backfilling. 5 [0048] Further, the foundation monitoring system 204 compares the first strength of the concrete foundation 106 with a pre-defined strength curve for the concrete foundation 106. The comparison is performed to determine expected strength of the concrete foundation 106 after 30 days. In an example, the first strength is analyzed that the percentage strength of about 60-65% has been achieved by the concrete
10 foundation 106. The prediction will show that 100% setting of the concrete foundation 106 will be achieved within 28-30 days for the concrete foundation 106. The first strength of the concrete foundation 106 is compared to confirm that the concrete foundation 106 has achieved desired percentage of strength. The concrete foundation 106 must acquire percentage strength according to the pre-defined
15 strength curve for the concrete foundation 106.
[0049] In an embodiment of the present disclosure, the foundation monitoring system 204 compares the first strength of the concrete foundation 106 with a pre-defined set of data.
