RESULTS OF EXPERIMENTAL RESEARCH ON OBTAINING LOW- CEMENT WALL MATERIALS FROM WASTE OF SAMING OF LOCAL LIME STONES

Abstract

The results of experimental studies are presented on the production of single low-cement modified dry-pressed bricks from limestone stone sawing waste from Martakert stone quarries. The technological parameters for the manufacture of these bricks and their physical and mechanical properties have been established. A high convergence of the properties of the resulting wall material was determined in comparison with ceramic and silicate bricks used in construction. Using the method of analogy, the compliance of the quality indicators of experimentally obtained bricks with the requirements of regulatory documents was proven. The fundamental possibility of producing low- cement bricks from stone sawing waste from local quarries, as well as their use in construction, has been established. The production of low-cement bricks makes it possible to increase construction efficiency and reduce the cost of operating completed facilities. This also leads to a reduction in environmental risks from the accumulation of stone sawing waste in large areas and pollution of the air and water basins of the region.
