This article is devoted to the study of pressed fine-grained basalt fiber concrete from mechanically activated raw materials mixtures based on limestone waste from stone mining. The microstructure of the pressed samples was investigated. A pilot test of the technology of mechanical activation and pressing of small-piece products was carried out. It is shown that bricks and paving slabs made using this technology meet the maximum requirements of GOST and have a brand of compressive strength of at least M400 (B30), frost resistance of at least F200, abrasion resistance of G1.
