METHOD OF PREPARING HIGH STRENGTH CONCRETE, HIGH STRENGTH CONCRETE AND CURED BODY

摘要

PROBLEM TO BE SOLVED: To provide a method of preparing high strength concrete capable of resolving problems of 1) and 2) at same time, where a) viscosity of concrete during preparation is high and flowability with time after preparation dramatically reduces (viscosity of concrete becomes high with time) and 2) enhancement of long term strength (compressive strength at 91 days of material age) of a resulting cured body is reduced when concrete is subject to a thermal history with temperature increase by heat generation during a process of curing by a hydration reaction, a high strength concrete obtained by the preparation method, a cured body obtained by curing the high strength concrete.;SOLUTION: There is provided a method of preparing high strength concrete by using low heat generating Portland cement, water, a fine aggregate, a coarse aggregate and following multifunctional admixture with percentage of 0.1 to 1.5 pts.mass of a specific multifunctional admixture containing a specific 3 components at a specific ratio per 100 pts.mass of the low heat generating Portland percentage.;COPYRIGHT: (C)2015,JPO&INPIT
