Steel fiber reinforced concrete is a new type of multiphase composite material formed by mixing short steel fibers in disorderly distribution in ordinary concrete. These randomly distributed steel fibers can effectively hinder the expansion of micro-cracks and the formation of macro-cracks in the concrete, significantly improve the tensile, flexural, impact and fatigue resistance of concrete, and have good ductility.
Steel fiber reinforced concrete is a cement-based composite material composed of cement paste, mortar or concrete as the matrix and composed of metal fiber reinforced materials. It is a new type of building material formed by uniformly dispersing short and thin metal fibers with good properties such as high tensile strength, high ultimate elongation and high alkali resistance in the concrete matrix. The bridge deck pavement, as the non-main structure of the bridge, is usually ignored in the design and construction. The effect of long-term vehicle load is the main reason for the cracking and damage of the bridge deck, which affects the quality of the bridge and reduces the service life. The use of steel fiber reinforced concrete for the surface pavement will effectively solve the quality problems that are easy to occur during the use of the bridge deck.
