Experimental Study on Characteristics of Polyacrylic Fiber Concrete

In combination with hydroelectric engineering, an experimental study on the characteristics of polyacrylic fiber concrete is performed. The result shows that the mixing of a certain amount of polyacrylic fiber into concrete is an effective way to prevent concrete cracking. An effective two-degree reinforcing effect of the disoriented supporting system in fiber concrete on concrete strength may help improve anti-crack performance, impermeability, impact resistance, and abrasion resistance of the concrete. Therefore, the adding of a certain amount of polyacrylic fiber to concrete can effectively improve the general performance of concrete.
