Abstract: The paper presents the results of the study devoted tothe reduction of perlite wastesin size in a vortex jet mill, as well as their reduction features. The bonding compositions were obtained at various ratios of cement and perlitesand wastes in a vortex jet mill at different reduction modes. Peculiarities of reduction processes were studied and technological and physical-mechanical properties of obtained bonding compositions were defined. The electron microscopy made it possible to study microstructures of cement stones received from taggedPortland cement and bonding compositions in a vortex jet mill. It was established that the open pores of cement bonding compositions prepared using perlite aggregates are always filled with new growths at various stages of collective growth. The microstructure of bonding compositions has dense structure due to rationally selectedcontent, use of effective mineral aggregates, i.e. perlite wastes thus creating additional substrates for the formation of an internal microstructure of a composite, mechanochemical activation of raw mix allowing obtaining composites with prescribed properties.
