The report is about the examination of the relation between the maturity and the compressive strength of steam curing concrete (W/C : 50%) at various temperatures. The principal results of the examination are as follows. 1. When cured below 80℃, The compressive strength of steam curing concrete on remolding (age : one day) is proportionate to maturity. 2. The compressive strength after one day aging widely varies depending upon the curing temperature and curing method after remolding, and therefore compressive strength is unproportional to maturity. 3. The relation between the curing temperature and the compressive strength indication ratio, γ (Fc/log t・log h) can be indicated, Loss's formula. 4. The formula for estimating compressive strength for sand-gravel concrete is as follows. (i) The case of water curing afer remolding, [numerical formula] (ii) The case of atmospheric curing after remolding, [numerical formula]
