Description

The subject of the invention is a method for making groundless clay-sandy kirniches, blocks, tiles, and other articles by molding, followed by steaming using complex calcined clay, lime, gypsum, and fillers from sandy and other materials.

A distinctive feature of this method is concluded; -; Mixing the mass of clay solution. The technology for making such a brick and block is as follows. The sand, prokalein clay, lime and plaster giis dry and mixed with P5 and kneaded with a clay mortar. The resulting dough is pressed into molds on a press under a pressure of 50-100 kg / cm. Otiress bricks or blocks are put in a shed where they are kept for 4-7 days, or, steaming without pressure on the bridegroom for 6-8 hours, after which they can be used in construction.

The following composition is recommended for the production of unburned bricks: river sand or gully, or granulated blast furnace slag, boiler slag, ground, brick side and. 60-70%; clay of cheese 5-10%; glial calcined 15-20%; lime kettle or fluff 2-3%; plaster plaster 1-2%.

The bricks made in the manner described or the seyorlle blocks have a temporary compressive strength of 100-150 and fully satisfy the requirements of the standard for building bricks and wall blocks.

In the production of the brick or block according to the described method, labor consumption is sharply reduced compared with the production of ordinary bricks. From the proposed material, it is possible to manufacture not only wall materials, but also the production of various building parts, etc.
