Key properties of steel fiber reinforced concrete and steel fiber

Jan 21, 2017

Added steel fibers can produce a variety of steel fiber reinforced concrete, wider range of applications, some highways, airport pavement can be used, enhancing performance, first look at the effect of steel fiber.
Steel fiber of enhanced effect main depends on matrix strength (FM), fiber of long diameter than (steel fiber length l and diameter d of ratio, that I/d), fiber of volume rate (steel fiber concrete in the steel fiber by accounted for volume percentage), fiber and matrix between of bond strength (τ), and fiber in matrix in the of distribution and orientation (η) of effect. When steel fiber concrete that most fibers are pulled out and not pulled off, thus improving steel fiber and the matrix is to improve the bond strength between fiber-reinforced the main control factor.
