RAW MIX AND METHOD FOR PRODUCTION OF CONCRETE FROM IT Russian patent published in 2010 - IPC C04B28/08 C04B40/00 C04B111/10 C04B111/20 

FIELD: construction.

SUBSTANCE: invention is related to the industry of construction materials, namely to compositions of raw mixes and methods for concretes making from it. Raw mix contains the following components, wt %: slag filler - blast furnace granulated slag 40-52, hardening controller - calcium sulfate dihydrate - 4-7, hardening activator - sand, containing 10-15% of minerals garnets - 5-10, complex additive for concretes "Relamix. Type 2" 0.2-0.4, slag binder - electric furnace slag - the rest. Method for production of concrete from specified raw mix includes tempering, mixing, crushing of construction mix in foundry chasers to produce liquid movable mass, its pouring in die moulds and hardening.

EFFECT: increased strength of concrete for compression and bending, and also increased water resistance and frost resistance.
