Possible solutions to problems in the cement industry

Abstract

In this paper, we substantiate approaches to the transition to clinker-free binders and building composites with their use to replace resource-intensive cement, at least in those areas of construction where its high technical functional properties are not needed. The optimal formulations and properties of alkaline activation binders based on mineral powders are revealed and the theoretical foundations of the formation of the structure and strength of cement stone based on an alkaline activator are revealed. The results of the studies are of practical value for the construction industry, as the obtained formulations of clinker-free cements will partially replace expensive and energy-intensive Portland cement in the production of concrete and reinforced concrete structures. This work was carried out as part of research on the implementation of scientific project No. 05.607.21.0320. "The development of technology for new building composites on clinkerless alkaline binders using substandard natural and secondary raw materials"that received support from the Federal target program "Research and development in priority areas for the development of the scientific and technological complex of Russia for 2014-2020".
