摘要
PURPOSE: An early strength concrete composition including a high-early-strength admixture is provided to maintain a cure temperature of concrete without a heater, and to reduce the total construction time at the construction site.;CONSTITUTION: An early strength concrete composition contains water, aggregate, cement and high-early-strength admixture powder. The high-early-strength admixture contains 40~70wt% of calcium aluminate with the blaine surface area of 7,000~10,0000 square centimeters per gram, 15~30wt% of inorganic sulphate with the blaine surface area of 6,000~9,000 square centimeters per gram, 10~25wt% of calcium carbonate powder with the blaine surface area of 3,000~6,000 square centimeters per gram, and 0.1~10wt% of cellulosic fibers.;COPYRIGHT KIPO 2010
