Description

f

The invention relates to the production of building materials and can be used in the production of alkali-silica in concrete and mortars and concretes based on them.

The purpose of the invention is to increase the strength and water resistance.

Example. The following components are used for the implementation.

Soda - alkaline component - calcination (TU 6-18-171-78), chemical.

becoming: Ca 80; Na 15; SO 5. Soda vvoO

Diatomite - the main component of the companion (TU), chemical. composition: SiO 82.6; ,four; CaO 1.9; 11.1. The specific surface is 1200-1500. Its introduction is determined by the number of other components. When its content in the mixture is too low, a sufficient amount of compounds is not reached, and a higher content leads to a decrease in strength due to the lack of an activator.

The introduction of additional alkaline comdates into the known composition in order to form, when interacting with silicate lump and chromate barium, an excess amount of insol- ation (5 elements (silicate lump) and additives, poured compounds, which leads to an increase in durability and water resistance. The introduction of water and water resistance by forming it into a mixture below 5% is the lack of high-molecular complex- sufficient for the flow of these compounds of the type pirsonit (hellu process, i.e., leads to a decrease in these sit ) H, 0 (5) and bi-indices, and above 10% - to a reduction in barium chromate, which create rigidity due to an increase in the content of insoluble water-resistant compounds.

Silicate lump - other alkaline Diatomite and silicate lump subject to component (GOST 130-79-81) - R O n 25 are co-milled to specific Sic ,,,, where, 6-3. It is introduced for a surface of 4000-4500. In the course of soda activity and stabilization of strength properties due to the formation of inorganic polymers. Introducing it into the mixture below 2% is not enough for the process to proceed, i.e. leads to a decrease in water resistance and strength, and more than 6% is irrational due to an excess of water-soluble i component.

All dry ingredients are mixed and shut off with water at, 45-. 0.5 Samples are formed by vibrating with a weighting of 0.02 MPa. To determine the water resistance, samples are prepared from a mortar 3x3x39 cm in size. To determine the strength, balances 4x4x16 cm from a 1: 1 solution (sanding: VOLSKY sand). Water resistance is determined by boiling in water for 2 hours, and the softening coefficient is determined as

Diatomite - the main component of the companion (TU), chemical. composition: SiO 82.6; ,four; CaO 1.9; 11.1. The specific surface is 1200-1500. Its introduction is determined by the number of other components. When its content in the mixture is too low, a sufficient amount of compounds is not reached, and a higher content leads to a decrease in strength due to the lack of an activator.

The introduction of additional alkaline components (silicate lumps) and the addition of barium chromate to the known composition in the substrate makes it possible to increase the strength and water resistance by forming high-molecular complex compounds of the type Pirsonite (geylu-0sit) H, 0 (5) and barium bichromate, which create a rigid structure of insoluble compounds.
