Abstract
The article reflects the main methods and methods for the study, research and application in the industry of building materials of a natural fossil, diamondite, related to siliceous rocks. The objective of the scientific study of diatomite in the Western region of Kazakhstan is to analyze the possibility of using diatomite in the production of building materials such as lightweight concrete products and structures with good thermal conductivity properties with a small bulk and sufficient strength. The purpose of the research is to develop a technology for the production of lightweight concrete products and structures based on diatomite for modern civil and industrial construction in the Republic of Kazakhstan. Diatomite was studied as an independent material and as a raw material for the manufacture of thermolith used as a filler for the production of building materials (light concretes), such as thermose and thermolith concrete. The physico-mechanical properties of laboratory concrete samples of thermite and thermolith concrete were studied by laboratory studies using instruments and equipment from the University's laboratory for building materials. The thermolith was manufactured in laboratory conditions by high-temperature roasting of the flask at a temperature of 1150°C. As a result of the conducted scientific research, the main physical and mechanical properties of thermite and thermolith concrete were determined.
