Fiber reinforced cement based composite material for reinforcing reinforced concrete structure
The invention relates to a high-performance fiber reinforced cement based composite material for reinforcing a cracked reinforced concrete structure under severe environments, and belongs to the technical field of building materials. The composite material is formed by mixing cement, silica powder, swelling agent, water reducing agent, fine sand, fiber and water, wherein the total mass percentage of cement, silica powder, swelling agent, water reducing agent, fine sand and fiber is 77.6% to 88.0%, and the mass percentage of water is 12.0% to 22.4%. The composite material designed by the invention has higher elasticity modulus, higher tensile strength and compression strength, higher self-healing capacity and low permeability. The material is reasonable in component design, simple in construction and maintenance and convenient for large-scale application.
