Using AE (acoustic emission) devices, it has been found that starting at point B microcracks develop in the rock sample and the sample experiences strain hardening. The ordinate of point B is called the yield stress by analogy with the response of concrete samples.

Basalt fibers (BFs) are made from basalt ores, which have the advantages of a low production cost, high tensile strength, high modulus of elasticity and good corrosion resistance [28,29,30]. In addition, BF has better compatibility with cemented materials due to their similar chemical composition [31,32].
