Development and research of complex modified concretes of a new generation for non-heating and low-temperature technologies based on local raw materials

Abstract

The article presents the results of the development and research of complex modified concretes of a new generation intended for use in heat-free and low-heat technologies based on local raw materials. Approaches to the modification of concrete mixtures in order to increase their thermal stability and accelerate the strength gain at low temperatures are considered. The analysis of the effectiveness of the use of various additives, as well as the effect of the composition of concretes on their physical, mechanical and operational characteristics is carried out. Special attention is paid to the use of local mineral components to improve the environmental and economic efficiency of construction.
