Definition of Polymer Concrete: Polymer means the joining and combining of several small and identical molecules and the formation of a large molecule called a polymer, which is called the polymerization process. They use a combination of concrete with different chemicals; One of these materials and tasks is the use of polymers and a kind of polymerization of concrete. This type of material (polymer) while having high strength, has low weight and is resistant to weather conditions and shows good resistance to various pressures and loads. In general, polymer concretes can be considered as a combination of natural polymer fibers in the size of fine and coarse grains.
