Setting and Hydration Heat Development Characteristics with Binder Types
결합재 종류에 따른 응결과 수화발열 특성
Abstract
In this paper, setting and hydration heat development characteristics with three binder types, type IV cement+fly ash, type IV cement+slag powder and type IV cement + limestone powder. were investigate. As results, it was shown that the limestone powder decreased the initial setting time regardless of replacement ratio, especially the range of 20~50% replacement ratio, and the 2nd peak was shifted ahead when the limestone powder replacement ratio increased. But for the f1y ash and the limestone powder, contrary results were obtained compared with the limestone powder.
