Ceramic products and energy-efficient systems

Abstract

Abstract The energy efficiency concept incorporates energy conservation and durability components involved in the operation of buildings and cost considerations pertaining to the manufacturing and installation of materials. Ceramic brickwork offers the highest reliability and durability category, is not combustible and in terms of these parameters has advantages over other insulated facade cladding systems. Improving the thermophysical properties of masonry made of calcined ceramic products is possible through the use of heat-efficient ceramics and, in particular, porous ceramic stones. It is notable that the use of combustible additives does not enable the uniform distribution of porosity across the material while the high ash content of some additives reduces the quality of the ceramic crock. In this connection, it was decided that the use of exfoliated vermiculite of up to 0.5 mm fraction would be reasonable. A completed experiment made it possible to establish the optimal density of exfoliated vermiculite and a methodology based on the correlation between the properties of ceramic-vermiculite products and consumption of exfoliated vermiculite and ceramic product calcination temperature.
