Polymer concrete (resin concrete) is also known as polymer cemented concrete or alternative polymer concrete. It is also called plastic concrete because it does not use cement at all. A polymer concrete made of synthetic resin (polymer) or monomer as a cementing material and with a corresponding curing agent, sand and gravel as a cement material, a new type for quick repair or wear protection surface. Sometimes in order to reduce the amount of resin, it is often added to human filler silt. It is also called plastic concrete because it does not use cement at all.
