Abstract:

The goal of the proposed work is to investigate the application of nano-engineered polyurethane (NEPU) emulsions for latex modified ; concrete (LMC). NEPU emulsions are non-toxic, environment friendly, durable over a wide temperature range, provide better ; adhesion, high strength, less cracking, and compatible with all mortar types. One of the weak links in a cement-aggregate composite ; material is the bond between the matrix and the aggregates. To improve the performance of the alternative cement binder (ACB), the ; research team intends to develop a NEPU resin to act as an intermediary between the aggregates and the ACB matrix. The NEPU will ; be used to precoat the aggregates prior to their placement within the ACB matrix. When combined with the ACB and water, the ; unhydrated ACB particles embedded within the NEPU-coated aggregates will react with the surrounding matrix during hydration, ; providing an enhanced interfacial zone and corresponding improvement in the material properties of the hardened material. In the ; proposed work, the used of bio-based NEPU emulsion for LMC application will also be investigated.
