플라이애쉬를 사용한 수중불분리성 콘크리트의 수화열에 관한 연구

다국어 초록 (Multilingual Abstract)

The concretes cast in the sea water would be likely to be rich mix and mass concrete. Therefore it is important to check out the hydration heat of concrete and to reduce it to prevent the concrete from processing the temperature crack. Recently the antiwashout agent is used on underwater concretes for preventing from the segregation of concrete in the water. The experimental studies were done for the combined cement replaced by fly ash 30% unit weight of binder to study on the characteristics of hydration heat of antiwashout underwater concrete, and its characteristic was discussed by comparing one cast in sea water with another one in air. The present paper showed that the hydration heat of concrete replaced by 30% of fly ash was more significantly reduced than the normal concrete. The hydration heat of antiwashout underwater concrete was higher than that of normal concrete, but it was reduced lower than the normal concrete by adding fly ash.
