| 要旨 | INTRODUCTION It is well known that the strength development of concrete is a function of age, curing method and temperature during casting and hardening. Temperature has a marked effect on strength, for example, although a higher temperature increases strength at an early age, it may adversely affect it at the later age. A preliminary study on the effect of different constant curing temperatures during casting and hardening of high strength concrete was done and by using the maturity concept the strength development of concrete with different W/C ratios was compared. This report shows the strength development of high strength concrete within maturity about 15°D.D-840°D.D, including the comparison with a typical ordinary concrete. In summary , the maturity-strength relation varies in a systematic manner with curing temperature. This suggests that an alternative approach may exist for computing maturity which correlates more closely with the maturity-strength relation. |
