Compressive strength of concrete is considered it's most valuable property among the mechanical properties of concrete. The purpose of this study is to examine the correlation between accelerated strength and 28-days strength of normaly cured concrete for the early evaluation of concrete strength. The test methods of this study is Rapid hardening method for mortar with accelerating agency, Accelerated strength for concrete with 55C water and Rapid accelerated strength for concrete with accelerating agency and curing with 55C water. An outline of this test method is as follows. The high temperature curing to fast develop strength in a short term is applied to concrete or wet-screening mortar specimens. This accelerated strength value is compared with 28-days strength or concrete of the same source to derive a formula, which is then employed to calculate 28-days strength from the result of the accelerated strength test.
