Abstract:Matching certain properties of polymer concrete overlays and repair materials more closely with those of concrete can produce better compatibility between the resin-based material and the cementitious substrate. The key parameters of polymer concretes that are significant to this end include the resin type and loading, shrinkage properties, coefficient of thermal expansion, and modulus of elasticity. The approach used most often has been to minimize the resin loading requirements. This approach, by itself, imposes certain limitations on the type of products that can be formulated. In the course of work to develop shrinkage-controlled polymer concrete utilizing an unsaturated polyester binder, it was discovered that the shrinkage control agent contributes in an important way to the thermal and elastic properties of the material. This paper describes how this finding was used to develop polymer concrete that is more compatible with portland cement concrete.
