The effect of microbiological treatment on the technological properties of clays of different mineral composition

The influence of the culture of bacteria Bacillus mucilaginous on the structural-mechanical, rheological, drying and other properties of clay raw materials of various mineralogical composition was investigated. Bacterial processing of clay raw materials contributes to an increase in its dispersion and plasticity, a decrease in air linear shrinkage and a coefficient of sensitivity to drying, which makes it possible to shorten the drying cycle of products, reduce rejects during drying, activate the sintering process and reduce the firing temperature of products, as well as increase the strength of the semi-finished product and the finished product. ...
