Abstract
The possibility of using diatomite rocks of the Il'insky deposit in the ceramic brick production has been considered. The chemical and mineral composition of diatomite was determined, and its molding properties were studied. The effect of temperature on the degree of sintering of diatomite was established. The technology of brick production was developed. The main stages of brick production by the method of semi-dry molding are determined. The recommended molding parameters (moisture content and specific pressure of pressing) are proposed. The diatomite properties have been studied and the technology of producing bricks by the method of semi-dry forming has been developed. The samples of ceramic bricks of the grade M100 up to M400 with the medium density class – 1.2 have thermal characteristics, relating to the group of effective products with the coefficient of thermal conductivity of the masonry in the dry state in the range of 0.24 to 0.36 W/(m·°C).
