METHOD OF PRODUCTION OF CEMENT CONCRETE Russian patent published in 2004 - IPC

Abstract RU 2223241 C2

FIELD: production of concrete mixes and structures on base of portland cement. SUBSTANCE: proposed method is based on activation of mineral fillers by grinding, removing dust-like and clay fractions, selecting granulometry of coarse and fine fillers, consumption of cement and water-to-cement ratio, preparation of cement mix from said components and hardening of mix. Prior to preparation of concrete mix , fine and/or coarse silicate-containing filler is subjected to autoclave treatment with saturated steam at temperature of from 120 to 210 C continued for 1-8 hours. Only fine filler in form of quartz sand may be subjected to autoclave treatment; before autoclave treatment, quartz sand is ground in mill at power requirement of 1-6 kWh per ton, and dust-like and clay particles are removed. Filler is subjected to autoclave treatment in presence of lime or sodium hydroxide, water glass or portland cement in the amount of 0.4 to2.0%. EFFECT: enhanced strength, durability, freeze resistance and corrosion resistance. 4 cl, 3 tbl
