Nationality: Indian
Preamble:
The following specification particularly describes the nature of this invention and the manner in which it is to be performed.

Description of the invention: Field of the invention:
Presently high density masonry blocks are available for construction use; although they provide strength they have cavity and also have more weight. To overcome this problem, a new Two Component Hybrid Masonry block (brick) invented - which has low density & good strength, capability of water diffusion, high insulation, stronger framework and outer exterior.
Background of the invention:
A conventional concrete masonry unit - also called concrete block or cement block or foundation block - is a large rectangular brick used in construction, such blocks are made from cast concrete or cement and aggregate, usually sand and fine gravel resulting high-density blocks.
The problem of high density, heavy weight construction was solved after the AAC (Autoclaved aerated concrete) came into use. These blocks have been produced for more than 50 years, and it offers several significant advantages over other conventional cement construction materials, one of the most important features is, being its lower environmental impact. AAC's insulating capability, one of its advantages in construction is its quick and easy installation, because the material can be routed, sanded, or cut to size on site using standard carbon steel power tools. AAC bricks are changing the future of industrial, commercial and residential development everywhere. It has proved its superior quality in virtually all climatic conditions of the world.

Two-Component Hybrid Masonry blocks comprise of :-
1. Hollow Masonry blocks OR Concrete Masonry Unit (CMU) with strong edges which gives better strength for walls and can bear maximum weight on the edges.
2. Foam Concrete is a light weight fillings at the core which occupies hollow space of the block, ultimately gives support and strength from inside.
Overall combination of 2 component Hybrid masonry block has features as below.
a) Perform faster construction
b) Easy of working c) Long Lasting

d) Versatility of usage
e) Light weight
f) Sound proof
g) Cost saving h) Pest resistant i) Fire resistant
j) Earthquake resistant
k) Eco friendly in nature
1} Great savings in foundation and structural costs due to decrease in overall dead load
m) Savings in handling and transportation costs
n) Due to lightweight nature, Possibility of additional floors on old structures

Object of the invention:
The main object of the 2 component Hybrid Masonry Block is to invent Versatile Block for Construction to overcome the Drawbacks of currently available construction units like Concrete Masonry Units or Autoclaved Aerated Concrete.
The further object of the present invention is. to create Light weight versatile brick which is environment friendly and suitable for any construction area.
The further object of the present invention is to integrate features of the two different construction blocks, i.e. Hollow Masonry block and Foam concrete like AAC into a newly developed 2-Component Hybrid Masonry block.
The further objective of present invention is to design cost-effective which will save material cost to fill the masonry block cavity, disaster resistant blocks for faster and easier construction system, when compared to the other conventional construction systems.
The further objective of present invention is, together combination of these two components help to equally distribute overall load from the top to the entire block.
The further objective of present invention is, to reduce the labour cost by providing pre filled masonry blocks.

Statement of the invention:
Accordingly present invention 2 Component Hybrid Masonry Block, comprises:
1. A hollow Masonry block made of concrete or cement
2. Foam concrete in the cavity.
Working principal of the invention:
Concrete masonry blocks have been in existence for centuries. Revolutionary changes in
manufacturing technology and material sciences have made multi sized, shaped, colors and
textured blocks a reality. They are used as both structural and non-structural components and
have been the preferred building blocks all over the world.
The production of concrete blocks consists of four basic processes: mixing, molding, curing, and
cubing. It can be produced by using a wide variety of precast concrete products including
blocks, flat paver stones, and decorative landscaping pieces etc.
These new blocks promise to make building construction faster and less expensive, as well as
result in structures that are more durable and energy efficient.
Once the shape of Concrete Masonry Unit is finalized, Foam concrete preparation process
starts. Foam concrete preparation is closely similar to the formation of AAC {Autoclaved
Aerated Concrete) process.
This Foam concrete is then poured in the newly manufactured Hollow Masonry block. Allow
this mixture to dry. Now the two components are integrated with each other to form a single
unit. These and other aspects of the invention will become more apparent from following
detailed description of the drawing.

The invention concerns a concrete block, in accordance with the umbrella term of.requirement
1 and which demonstrates characteristics set out in this requirement.
Requirement 2 concerns the design of coating and hollow concrete blocks and the filling of their
hollow interiors with a fluid binding agent, preferably a mixture of light concrete with a density
of less than lkg/dm3.
Another important feature of the invention concerns a procedure in the manufacturing process
of the concrete blocks in accordance with requirements 1 and 2. The preferred manufacturing
procedure is outlined in requirements 3 and 4.
The invention is explained more thoroughly using the sketch: An oblique view of the new concrete block is shown in fig. 8A.
The concrete block in
Fig. 8A shows the length (I), breadth (b) and height (h).
Fig. 8B shows the inner bottom of the concrete block according to the invention and how the
interior hollow areas are filled with light concrete with a density of less than 1 kg/dm3.
Fig. 8C shows how the procedure for filling the concrete blocks according to the invention
works.
