Description

The invention relates to the building materials industry and relates to compositions of ceramic materials for the production of bricks.

Known ceramic mass containing, wt.%: Clay 76-79; coal 1-1.5; crushed brick scrap after drying 0.5-0.9; shredded fiberglass waste - the rest [1].

The objective of the invention is to increase the frost resistance of the brick obtained from the ceramic mass.

The technical result is achieved by the fact that the ceramic mass for the production of bricks containing clay, crushed marriage of bricks after drying, further includes quartz sand, carboxymethyl cellulose and glycerin, and the components are in the following ratio, wt.%: Clay 83.7-89.6; crushed brick scrap after drying 0.1-1.0; silica sand 10.0-15.0; carboxymethyl cellulose 0.1-0.2; glycerol 0.1-0.2.

The compositions of the ceramic mass are shown in the table.

To prepare the ceramic mass, high-quality clay (brick) of any deposits can be used.

Ceramic mass is prepared as follows.

1. The components are dosed in the required quantities. Moisturize and thoroughly knead clay. The marriage of the brick after drying is subjected to grinding until it passes completely through the mesh No. 008. The prepared components (clay, crushed brick scrap after drying, quartz sand, carboxymethyl cellulose) are mixed, water and glycerin are added. The moisture content of the ceramic mass is selected in the range of 18-23%. Brick is molded from the ceramic mass in a plastic way, which is dried to a moisture content of not more than 6% and fired at a temperature of 1000-1100 ° C.

2. The components are dosed in the required quantities. Clay is ground in a dry manner. The marriage of the brick after drying is subjected to grinding until it passes completely through the mesh No. 008. The prepared components (clay, crushed brick scrap after drying, quartz sand, carboxymethyl cellulose) are mixed, water and glycerin are added. The humidity of the ceramic mass is selected in the range of 9-13%. A brick is molded from the ceramic mass in a semi-dry manner, which is fired at a temperature of 1000-1100 ° C.

The ceramic mass is well molded in a plastic and semi-dry way. Products have the correct configuration.
