Abstract

The aim of this study is to predict concrete strengths by method of equivalent ages. The method of equivalent ages is to use Arrhenius equation which indicates the influence of curing temperature on the initial hydration ratio in cement. Experimental factors are in this study. The water-cement ratios of concrete mixtures are 0.60, 0.55, 0.50 and 0.45. The curing temperatures within the four chambers are 30, 20, 10 and 5$^{\circ}C$. The test results showed that equivalent age can be used to predict compressive strength of concrete at early ages.
