Polymer Concrete is a composite material in which the binder consists entirely of a synthetic organic polymer. When sand is used as filler, the composite is referred to as a polymer mortar. Other fillers include crushed stone, gravel, limestone, chalk, condensed silica fume, granite, quartz, clay, expanded glass and metallic fillers. It has good resistance to attack by chemicals and other corrosive agents and very low water sorption properties.
