SELECTION OF THE OPTIMAL COMPOSITION OF FIBER CONCRETE BASED ON BASALT FIBERS AND ANALYSIS OF PHYSICAL MECHANICAL PROPERTIES

At present, the demand for cheap materials and products from the energy-efficient economic side in the world construction sector is increasing. In this case, building materials made from local raw materials and industrial waste, first of all, save energy in the process of preparation, and secondly, due to the use of local waste, its cost also partially decreases [1]. At the same time, the use of secondary resources in order to rationally use the depleted resources is currently a topical issue.
