Description:FIELD OF THE INVENTION
This invention relates to Method for enhancing hydration and durability in masonry mortar using PEG 400 and AAC blocks Construction debris for internal curing
BACKGROUND OF THE INVENTION
Protection of intellectual property takes place through patent filings that simultaneously drive innovative material development in construction. Masonry mortar acts as the essential component which determines both the durability and structural integrity of masonry building elements. The research examines how Polyethylene Glycol 400 (PEG 400) concentrations at 1%, 2%, 3%, 4% and 5% when added by volume to cement affects the behavior of masonry mortar while using Autoclaved Aerated Concrete (AAC) block construction debris. Using internal curing with added moisture produces long-term hydration while it improves workability as well as durability characteristics and reduces shrinkage effects. The use of lightweight aggregate-based traditional internal curing agents faces both economic and environmental challenges when used in particular applications. Researchers studied how PEG 400 functions together with AAC debris components to affect strength development, water stability, and the efficiency of curing processes. Developing a sustainable mortar mix represents this work's main focus as it improves mechanical values and maintains hydrated conditions to increase service duration through green construction methods. Research outcomes from this study help produce sustainable construction practices that enable potential patent development for green masonry technology innovations.

Methodology:
Research methods for masonry mortar formulation evaluation include specific plans and procedures to assess internal curing enhancements. The research framework consists of these vital stages for evaluation purposes:

1. Performance deterioration occurs within traditional mortar since insufficient hydration leads to structural damage while reducing service life span. One major water retention limitation exists as a fundamental barrier against cement hydration completion and reduces the durability of long-term performance. Building waste production from the construction sector continues to rise which creates environmental trouble and depletes resources.
2. Building operators substitute debris materials to act as part of their fine aggregate content.
3. Researchers will apply factorial design to assess strength performance combined with workability properties combined with water retention capacity based on various waste material proportions.
4. The researchers will prepare several concrete mixes through diverse combinations of PEG 400 at different ratios between 1% and 5% together with sufficient binding agent levels.
5. Laboratory assessments will conduct standard tests for compressive strength, flexural strength and water absorption together with measures of shrinkage and durability of the materials.
6. The Response Surface Methodology (RSM) statistical tools will analyze the data through multiple design formulation methods to optimize formulation quality.
The research examines how Polyethylene Glycol 400 (PEG 400) concentrations at 1%, 2%, 3%, 4% and 5% when added by volume to cement affects the behavior of masonry mortar while using Autoclaved Aerated Concrete (AAC) block construction debris. Using internal curing with added moisture produces long-term hydration while it improves workability as well as durability characteristics and reduces shrinkage effects. The use of lightweight aggregate-based traditional internal curing agents faces both economic and environmental challenges when used in particular applications.
Material Proportions:
S.no Materials & Building Debris Material Proportion
1 Cement OPC43/ 53 Grade
2 Crushed AAC block Construction Debris 0-100% - Replacement of FA
3 Fine Aggregate (As per IS 383 Specification) River sand or Artificial sand
4 Water-Binder Ratio 0.40 - 0.50
5 Polyethylene Glycol 400 (PEG 400) 1%, 2%, 3%, 4%, 5% by cement volume

This work intends to create a masonry mortar with debris, maximizing hydration, reducing shrinkage, and improving durability. Combining PEG 400 and AAC building waste makes the modified mix composition sustainable and maybe patent- eligible for environmentally friendly masonry uses.
Description of Every Step:
1. Material Properties: Choose a suitable type of cement, like Ordinary Portland Cement (OPC) of appropriate quality. Choose sand that satisfies the necessary standards in fine aggregate.
Use AAC trash as a partial replacement for fine aggregate to support environmentalism.
For internal curing, find the ideal molecular weight—that is, PEG-400 or PEG-600.
Make sure the water is fit for mixing and clear.
2. Design & Proportioning Mix: Create mix designs with different PEG dosages—0%, 1%, 2%, 3%, 4%, and 5%. Keep mix water-to-cement (w/c) ratios constant. Change workability as needed to reach intended consistency.
3. Fresh Properties: Slump flow and flow table tests help to evaluate the workability of fresh properties. To find out how PEG affects setting behavior, measure both starting and ending times.
4. Curing Methods: To assess their influence on mortar qualities, apply many curing techniques, including PEG-assisted internal curing, air curing, and water curing.
5. Hardened Properties: Testing compressive and flexural strengths at predetermined intervals helps evaluate hardened properties. Test performance durability and water absorption to gauge environmental factor resistance.
6. Optimization Methods: Analyze data using statistical techniques, including artificial neural network (ANN) modeling and regression analysis, to project results.
7. Performance Evaluation & Suggestion: Find the best PEG dosage: Analyze if AAC trash would be appropriate for mortar compositions. Based on results, suggest uses for sustainable masonry.
