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, diamithite, related to siliceous rocks. The objective of scientific research of diatomite in Aktobe region is to analyze the possibility of using diatomite by construction organizations in modern civil and industrial construction, and to develop technology for the production of diatomite thermal insulation bricks. The purpose of the research work is to develop a technology for the production of energy-saving building materials based on diatomite from the Western region of Kazakhstan for modern civil and industrial construction in the Republic of Kazakhstan. The article highlights the nature of the origin of diatomite. The physico-mechanical properties of diatomite were studied by laboratory studies using instruments and equipment from the University's laboratory for building materials. 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. The thermolith was made in the laboratory 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 diatomite, thermolith and diatomite thermal insulation bricks were determined.
