What is Polymer Concrete?
Polymer concrete is similar to conventional concrete in that it contains selected blends of aggregates and fillers which are held together utilizing a binder. The aggregates include silica, quartz, granite, limestone and other high quality material. Conventional Concrete uses a combination of cement and water for the binder. In polymer concrete the binder is a high strength, corrosion resistant, thermosetting resin. This resin system requires a curing agent (catalyst) which when combined with the resin, transfers the resin and curing agent from a liquid to a solid (thermoset polymer) which bonds to the aggregate, various fillers and internal reinforcement. The polymer concrete is reinforced with fiberglass for superior strength and rigidity.
