Effect of SO 3 Content on Hydration of Cement Containing Triisopropanolamine

Increasing SO 3 content helps to improve the early strength of triisopropanolamine cement,The results of hydration heat analysis show that the addition of SO_3 to TIPA-containing cement,The reaction rate of cement hydration increases ,The cumulative heat release increased and the degree of hydration increased after 3 days of hydration.The transformation of AFt-AFm was inhibited.Compared with the hydration of cement containing TIPA,Sulfate promotes the whole silicate phase (C 3S + C) when the addition of SO 3 is 0.6%.2 S) Early hydration produces more Ca (OH) 2 (CH) involved in C 4 AF Hydration, to a certain extent, promotes the reaction to produce more AFt, and the cement paste produced by adding SO 3 is more compact.
