Activation of slag blended cements by amines - CHRYSO

Jul 27, 2021· The use of activators containing amines can help to compensate this performance loss. During this study, Amine 1 and Amine 2 were incorporated in a cement blended with 40 wt% slag at a dosage of 0.1 wt% in dry active matter. The quantity of amine adsorbed per blended cement specific surface was measured at 10 minutes, 1 and 2.5 hours of hydration.

Jan 01, 1999· Whereas for Portland cement the standardized curves q/q max are independent of the temperature θ 5, 6, it seems that for blast-furnace slag cement a single function for describing the effect of the state of the hardening process on the heat production does not exist. The reason can be found in that the hydration of slag cement is composed of ...
