Abstract
Improving the quality of bricks semi-dry pressing made on the basis of clay raw materials of the Kagalnik-3 field
Incoming article date: 02.08.2016Results of researches on improvement of quality of the brick made of clay Kagalnik-3 raw materials are presented. It is defined that raw materials contain a large number of particles less than 1 mm in size that complicates receiving press powder of the recommended granulometriya. In addition, because of high sensitivity of raw materials to drying, on samples there are drying cracks influencing durability and frost resistance. It is defined that for receiving qualitative products, except softer mode of drying, for increase in physico-mechanical characteristics it is necessary to add the mineral modifying additive to furnace charge, and to carry out preparation of press powder with preliminary plastic granulation of weight.
