Strength Development In Mass Concrete And Proportioning Strength Of Concrete Using Low-Heat Cement

摘要

The strength development of concrete using low heat cement, i.e., fly ash cement, moderate heat portland cement, etc. In massive structure are investigated based on the data of some experiments carried out in past time. The difference in strength between concrete in structure and concrete specimen for quality control cured under the same temperature history in the structure are compared. The correction coefficient of concrete strength to determine the proportioning strength cured under high temperature in early age in massive structure was proposed based on this investigation.
