Study of Concrete Strength Prediction Using Warm Water Curing

Article Preview

Abstract:

In this study, the 50°C warm water is applied to accelerate curing of concrete and to increase the design strength to 210kgf/cm2 (3000psi), 280kgf/cm2 (4000psi), and 490kgf/cm2 (7000psi) by using water/cement (w/c) ratio of 0.6, 0.5, and 0.35 respectively. The result shows that it takes only 2~5 days to reach the design strength with warm water curing instead of 28 days by standard curing. Three type of specimens may reach 1.0~1.05 times of target strength. As a result, a modified coefficient factor for design of concrete strength can be predicted more accurately and much earlier during curing process of the concrete.
