PRODUCTION OF CLINKER BRICK ON THE BASIS OF MINERAL RAW MATERIALS OF THE REPUBLIC OF BELARUS
Abstract
Mass compositions for production of dense ceramics, in particular clinker bricks based on low-melting clays, loams, low-calcined chamotte and cullet glass have been developed. A positive effect of finely ground low-ash chamotte obtained by heat treatment of low-melting clays at 1000 °C, which contributes to the expansion of the sintering interval of materials, is established. The complex use of polymineral clays, low-calcined chamotte and loams allows obtaining dense-looking material with a water absorption of 3–5 %, which is due to the effective action of fine-dispersed amorphous silica contained in loam. Dense material with a less than 5 % water absorption, frost resistance of 120–200 thermal cyclings and mechanical compressive strength of 41–47 MPa was produced by calcination of the mentioned materials at 1150 ± 10 °C.
