Abstract

This study investigated the effects of various factors on the applicability of static modulus of elastic to early determination by warm water curing at 40℃. As a result, it was clarified that even if pre-curing time, type of coarse aggregate, Bulk volume of coarse aggregate per unit volume of concrete and concrete temperature were different, static elastic modulus of concrete using various cements could be estimated by the linear equation.
