Problems solved by technology

The disadvantage is large shrinkage and poor durability when hardened. At the same time, the existing polymer concrete (PC) needs to achieve its planned effect. The amount of polymer binder (ie resin) is usually controlled at 9-25%. However, PC The nature of the resin mainly depends on the type and performance of the polymer binder, the performance of the aggregate, the performance of their raw materials and the formulation technology. At present, the content of resin controlled in PC can only reach ≥8%, generally 12-15%. It is impossible to further reduce the content of resin in PC, which has become a major problem restricting the development of PC
