AbstractHydration of Csub3S and portland cement at water/solid ratios of 0,25, 0,40 and 0,70 and methanol contents of 0, 1, 6, 4 and 8 per cent has been studied using DTA, TGA, DTGA and conduction calorimetry. It was found that methanol retards hydration, and there was evidence of interaction between the hydrated products and methanol. For cement, setting times increased and compressive strengths decreased up to 28 days at all dosages of methanol.
