Polymer Concrete

Polymer concrete, also known as Epoxy Granite, is a type of concrete that uses a polymer to replace lime-type cements as a binder. In some cases the polymer is used in addition to Portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC).[1] Polymers in concrete have been overseen by Committee 548 of the American Concrete Institute since 1971.

In polymer concrete, thermoplastic polymers are often used,[2] but more typically Thermosetting resins are used as the principal polymer component due to their high thermal stability and resistance to a wide variety of chemicals. Polymer concrete is also composed of aggregates that include silica, quartz, granite, limestone, and other high quality material. The aggregate should be of good quality, free of dust and other debris, and dry. Failure to fulfill these criteria can reduce the bond strength between the polymer binder and the aggregate.[3]

Polymer concretes commonly known as Epoxy granite are distinct in composition only in that the polymer used is exclusively Epoxy
