Open publisher page 0 citations

Abstract

High strength concrete has high heat of hydration and poor workability before setting resulted from significant slump loss due to a large amount of cement content and low water cement ratio.'Results of this study showed that properties of concrete containin GGBF(ground granulated blast-furnace) slag varying fineness, GGBF slag-cement ratio, age and cement content are slightly different from those of conventional high strength concrete. The maximum compressive strength at age of 28 days was . In addition, compressive strength, tensile strength and elastic modulus of concrete made with GGBF slag 30% replacement cement showed higher value than that of concrete not containing GGBF slag.
