Influence of mixing temperature on the fluidity of mortar was investigated with special emphasis on mineral composition of cement. Fluidity of mortar made from the cement containing 70 % belite was compared with that made from other cements containing various amounts of belite. Hydration of cements, adsorption of super plasticizer and zeta potential of cements were stuided for analysis. Influence of temperature on mortar flow and flow loss decreased with increasing belite content and decreasing interstitial phase in cements. This is explained by increase in zeta potential, decrease in BET specific surface area, and decrease in ettringite content after initial stage of hydration.
