Copper plated steel fiber

It is a high-tech concrete compounded with DSP (Densified System Containing Ultra-fine Particles) and fiber-reinforced materials. According to its composition and heat treatment method, the compressive strength of this concrete can reach 200MPa to 800MPa; the tensile strength can reach 20MPa to 50MPa; the elastic modulus is 40Gpa to 60Gpa; the fracture toughness is up to 40,000J/m2, which is ordinary concrete. 250 times, comparable to metal aluminum; chloride ion permeability is 1/25 of high-strength concrete, strong resistance to penetration; after 300 fast freeze-thaw cycles, the sample is not damaged, the durability factor is up to 100%; prestress The ratio of the flexural strength of the reactive powder concrete beam to its own weight is close to that of the steel beam. The application of RPC in engineering structure can solve the shortcomings of high tensile strength, brittleness and poor volume stability of high strength and high performance concrete. It can also solve the problems of high investment in steel structure, poor fire resistance and easy corrosion. .
