CEMENT ADMIXTURES FOR ENHANCING COMPRESSIVE STRENGTH AND CEMENT COMPOSITION USING THE SAME

摘要

PURPOSE: A cement admixture for strength reinforcement is provided to enhance compression strength of cement by containing titanogypsum, limestone, and purified water sludge in an optimal ratio. CONSTITUTION: A cement admixture for strength reinforcement contains 25-50 weight% of titanogypsum, 25-50 weight% of limestone, and 25-50 weight% of purified water sludge. The admixture is plasticized through heating and a plasticizing temperature is at 900-1200 degree C. A cement composition comprises cement and the cement admixture for strength reinforcement. The cement is slag cement. The cement admixture for strength reinforcement is mixed with the cement with a ratio of 7-10 weight%. A production method of the slag cement includes the following steps; (a) a preprocessing solution is prepared by mixing a stimulant into water; and (b) a blast furnace slag is pulverized after spraying the preprocessing solution onto the blast furnace slag. The stimulant contains at least one among hydrogen peroxide, aluminum sulfate, and sodium thiosulfate. [Reference numerals] (AA) Titanium; (BB) Sludge; (CC) Limestone
