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.
