Description

The invention relates to the field of technology of silicates and relates to compositions of ceramic masses for the manufacture of bricks used in construction.

Known ceramic mass, including, wt.%: Clay 50-60; silica sand 40-50 / 1 /.

Known ceramic mass containing, wt.%: Clay 20-30; quartzites 70-80 / 2 /.

The aim of the invention is to increase the strength of the brick.

The goal is achieved by the fact that alumina and technical lignosulfonate are additionally introduced into the composition of the ceramic mass containing clay and quartzites in the following ratio of components, wt.%: Quartzites 25-30; alumina 3-5; technical lignosulfonate 0.01-0.02; clay rest.

The table shows the composition of the ceramic mass.
