Recently, it is common to use mineral admixtures in cold weather concreting. therefore, this study measured slump, air-contents and loss depend on elapse time on replacement fly-ash 10% concrete with set-accelerating tablet. then compressive strength at early age has measured. As a result, slump of fresh concrete according to elapsed time is Tablet 0.5%, 1.0%, 1.5% and was similar to that of the control and plain. also air-contents wasn’t affected. all early strength at 24hr is more good than control and plain. especially, ratio 1.0% was the most excellent.
