Annotation:

Results of laboratory tests of prisms with different by size aggregates are presented in the article. Dependences of bending strength and moment of crack appearance in the fibrous concrete specimens on type of aggregate are defined. Diagrams of “load – bending” of considered variants are plotted. An analysis of the results of laboratory studies is fulfilled. The influence of silica microparticles as a mineral additive on the strength properties of fiber-reinforced concrete specimens is shown.
