Abstract

The influence of the volume fraction of high-strength fiber on the mechanical characte­ris­tics and acoustic emission (AE) of reinforced concrete beams during their three-point bending test was studied. A criterion for AE optimization of the volume fraction of high-strength fiber to ensure the maximum tensile strength of composites based on a concrete matrix is proposed, which is the minimum value of the strength coefficient – the ratio of the tensile strength of the composite to the stresses of the beginning of the ge­neration of AE signals accompanying shear fracture mechanisms. Numerical values of this coefficient were established for fiber concrete with basalt and steel fibers.
