The addition of blue steel strip steel fiber concrete can effectively hinder the expansion of concrete micro cracks the formation of macro cracks, significantly improve the tensile, bending, impact fatigue properties of concrete. The addition of waterproof agent in steel fiber concrete has the advantages of moisture-proof, crack resistance wear-resistant, which plays a good role in the waterproof of basement civil air defense project. It can also be used for waterproof of underground water pump. Concrete is a new type of polyphase composite material formed by adding short fiber randomly distributed into ordinary concrete. The tensile, bending, impact resistance, fatigue resistance of concrete are significantly improved, the concrete toughness is better. It is widely used in the construction of modern water conservancy hydropower projects. Steel strip manufacturer
