抄録

 In the present study, the hydration reaction in the early age for blast furnace slag cement (BB) and the cement paste of BB mixed with a lime-based expansive admixture was investigated based on different temperature histories. The relation of interdependence between alite and belite was slightly different depending on the existence of expansive admixture, and it was confirmed that the initial hydration reaction rate of the belite mixed in expansive admixture was high. Reaction rates of blast furnace slag(BFS) and alite have high correlation regardless of the curing temperature and the temperature history. Moreover, the possibility of the dependency between the reaction rates of BFS and alite was implied since the dissolution and precipitation equilibrium in the liquid phase. From the high correlation between the downward trend of the Ca/Si ratio and the reaction rate of slag, it was deduced found that the BFS as a source of SiO₂ of C-S-H was functioning.
