Description

one

The invention relates to the building materials industry and can be used in the manufacture of structural materials and floor slabs.

The purpose of the invention is to increase the strength and reduce water absorption and abrasion.

PRI im p The granulated waste of coal-felled production (bead) is a filler, and crushed to a fineness of 4000-4500 is one of the components of the binder.

I

The chemical composition of mineral wool production waste: SiO 39.54;

 11.87; FeO 1.58; TiO, .0.34;

 0.03; MnO 1.53; CaO 39.7;

MgO 4.21; Z.RI.O 2.00. The presence in the filler of the bead allows you to create a monolithic structure of the material due to the homogeneity of the pitcher (finely crushed corols) and the pad and strengthened it as a result of the interaction of calcium hydroaluminosilicates in the pitcher and the pad. It also reduces open porosity and, accordingly, water absorption. The use of korolok within the specified limits allows you to dispose of waste mineral wool

manufacture and reduce material cost.

The mass is prepared as follows. Kings are crushed in a ball

5 mill to 4000-4500 cmVr for 5 min. Separately grind silicate-lump to size 2000-3000 within 3-4 minutes. Then mix them in a ball mill for about 1–2 minutes. This mixture is placed in a paddle stirrer, to which quartz sand and granulated waste are added and stirred for 2-3 minutes, mixed with water B / T

i; j 0.35 and stirred again for 2 minutes. They are shaped by vibropressing 0.02 MPa, placed in an autoclave and steamed under the 2 + 8 + 3 mode and at 8 at,
