SU1004299A1 - Raw mix for preparing cellular concrete - Google Patents

Description

The invention relates to the washing of building materials and can be used for the production of autoclaved cellular concrete.

CMecis foam concrete, containing portland cement, silica aggregate, foaming agent, spent synthetic slag of electric smelting production Cl.

Close to the invention is a concrete mix, containing-; pressed slate phosphate, lime, cement, gypsum, potash, aluminum aluminum Aerated concrete from this mixture has a compressive strength of 50-105 kgf / cm2 and a bulk weight of 700-1100.

The disadvantages of lime mixes are low strength and high cost of products.

The purpose of the invention is to increase the strength of cellular concrete products and reduce costs.

This goal is achieved by the fact that the raw material mixture for the manufacture of cellular concrete, including 1 YLT granulated electrothermoforsforny slag, activator, lime-containing component, aggregate, gypsum and alia | Nye powder, contains as an activator carnallite or a salt,

Phosphoric slag. The technology for making cellular concrete is as follows.

Phosphoric slag and lime (dolomite, jointly grind, to a specific surface of 35 x O-4000, low quartz sand is ground to a specific surface of 1500-2000 CMVr.

Shutter water temperature. is 7b-80 ° C. The components of phosphoric slag, lime, sand and gypsum in a certain ratio of feathers are sewn with water for 2 minutes to obtain,

homogeneous mass. The activator is introduced with the water of the land. Aluminum powder is injected after obtaining a homogeneous (essay. The mixture is poured into a form-size 10x10x10 cm, cut the top crust and samples are steamed in an autoclave at an overpressure of 1x) MPa at 2x12x2 hours.

The reduction in the cost of 1 m of the LI product on phosphoric slag is 8 rubles. 62 kopecks in comparison with products on cement in the grip.
