To the Question of Fiber Reinforcement of Concrete

Abstract:

The question of adhesion of fibers with a cement matrix is considered. Under certain conditions the fibers connect and hold the places of potential breaks. The important characteristics of fibre fibers are: surface texture, cross-sectional shape and construction in the longitudinal direction of the fiber. A sufficient number of fibre fibers located in the direction of the acting force can take the tensile force after the rupture of the matrix. The question of the fiber content in the percentage of the volume, which is sufficient to increase the strength, is considered. The properties of the finished concrete mixture and the adhesion of the fiber and the concrete matrix depend on the parameters. As a rule, there is a poor adhesion of smooth steel fibers in the cement stone.
