Matrix strength is one of the main determinants of the strength of polypropylene crack-resistant fibers. The ratio of length to diameter of the fibers, the distribution of the fibers in the matrix of other industrial products, and the bonding strength between the matrix are all determinants of the strength of the fibers. Therefore, we want to enhance the strength of anti-cracking fibers, which can enhance the degree of adhesion and strength between the fibers and the matrix, so as to prevent the fibers from being pulled out of the matrix.
The place where polypropylene crack resistant fiber is used more is concrete. According to the above measures to improve its strength, adding it to concrete can greatly enhance the flexibility and crack resistance of concrete.
