Abstract

The article presents the results of experimental studies of the influence of granite dust on the properties and durability of concrete. The use of industrial waste – granite dust, in the processing of granite into crushed stone, at the same time allows the rational use of natural resources and solve environmental problems. The possibility of improving the construction and technical properties of concrete filled with granite dust is considered. Experimental-statistical models of technological and physical-mechanical properties of concretes are presented and analyzed, ways of their improvement are shown. The complex of strength properties, water absorption, frost resistance, and durability of such concrete have been studied. The studied concrete are characterized by a more intensive set of strength and obtaining mixtures of “sticky” consistency. Due to the partial replacement of sand by granite dust, the microstructure of the cement matrix is compacted, which is the main reason for reducing porosity and increasing the durability of structures based on the proposed concrete.
