Recently, it has continuos studied about the earlier evaluations of the concrete strength in terms of accelerated curing at home and abroad. For this study, we present an accelerated-curing method by warm water method and discuss how these methods can be adapted for regular quality control and quality assurance of concrete. An accelerated-curing method to predict the 28-days strength of concrete, from 24-hours warm water-cured test result was evaluated in the laboratory. The relationship between 24-hours and 28-days compressive strength is obtained by regression analysis. The result of analysis can be obtain following equation. Y = 1.38X + 31.51
