Description

(S) CHARGE FOR MANUFACTURING BUILDING PRODUCTS

The invention relates to building materials and can be used in the manufacture of road blocks, wall and facing materials.

The known charge for obtaining road block, which includes the following components, may. %: ground marl triple 35-77. caustic soda and sand (fractions 0.6-1.25 mm) 20-60 til

The strength of the road checkers from this mixture is 260-330 MPa, but the temperature is sintering. This mixture, giving good strength, has a high firing temperature, which increases the consumption of thermal energy for the production of the material.

Closest to the invention is the charge for the manufacture of building products t2}, including the following components, May. %:

Quartz sand

Fly ash25-27

Aluminum Chromium Phosphate

binder 13-16

Chromomagnesite 15-19

The disadvantage of this composition of the charge is the production of products with low strength and abrasion resistance.

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

This goal is achieved by the fact that the charge for the manufacture of construction products, including quartz sand, fly ash and phosphate additives, contains, as a phosphate additive, chemical production waste, monozincophosphate and an additional waste product of caprolactam soda melt at the following ratio of components, May %:

Quartz sand 20-tO

All-Component Ash 3 All components that make up the mixture are industrial waste, with the exception of quartz sand. Soda melt - waste from the production of caprolactam - it has the following chemical composition, May. : 97.08; K20 Oh; FejO 0.2; CaO 0.2; MDO 0.12; SOg 0.3; C) Consumption of monozincophosphate ,. is- (O with the waste of chemical production, reduces the viscosity of the liquid phase, which is formed during the interaction during the burning of ash and sand with soda melt .. The ointment monozincofoephate has a chemical composition,%: ZnHPOj 97 98; 2-3.

Ta c ts a 2 4 Samples are made as follows. . Cylinder samples are formed from the initial components, which are calcined in a muffle furnace at 860-870 ° C and cooled after drying are tested for compression and abrasion. In tab. 1 shows the composition of the image ° in the results of testing the samples are given in table. 2. The application of the proposed charge will save thermal energy during firing products and increase their durability. The cost of products also decreases, since the charge consists of only production waste, except sand.
