INFLUENCE OF HIGH TEMPERATURE CURING IN AN EARLY AGE ON STRENGTH DEVELOPMENT OF CONCRETE USING HIGH-EARLY-STRENGTH PORTLAND CEMENT AND LOW HEAT PORTLAND CEMENT

Abstract

The influence of high temperature curing in an early age on the strength development of concrete was indicated in this study. The strength development of concrete using high-early-strength portland cement strongly depends on the curing temperature at the time of 0-3 hours since concrete is mixed up. The strength development of concrete using low heat portland cement depends on the curing temperature at the time of 0-12 hours since concrete is mixed up. High temperature curing after 72 hours since concrete is mixed up accelerates the strength development of concrete using low heat portland cement.
