RAW MIX FOR PREPARATION OF FROST-RESISTANT WALL BUILDING STONES AND MONOLITHIC WALLS Russian patent published in 2013 - IPC C04B38/10 C04B38/02 

FIELD: construction.

SUBSTANCE: raw mix for preparation of frost resistant wall building stones and monolithic walls, including a binder, a filler - an ash and slag mixture, a foaming agent, a chemical additive - Relamix. Type 2, calcium carbide, the binder used is represented by the following components jointly ground to the size of less than 250 m²/kg: an ash and slag mix from burning of coal in furnaces of a boiler house or a thermal power plant cooled by dry method, a hardening activator - alkaline reagents of sodium or potassium, or carbonates of these metals or lime or mixtures of the specified reagents, and calcium sulfate dihydrate, and the filler is an ash and slag mixture from burning of coal in furnaces of a boiler house or a thermal power plant, cooled by the dry method, and clay, and additionally the mixture contains spent engine oil, at the following ratio of components, wt %: specified ash and slag mixture for a binder 14-19, specified activator of hardening 3-6, specified calcium sulfate dihydrate 4-6, foaming agent 0.3-0.6, Relamix. Type 2 0.1-0.2, calcium carbide 0.5-4.0, clay 5-10, spent engine oil 0.2-0.4, specified ash and slag filler - balance.

EFFECT: improved frost resistance of products from the proposed mix.
