Abstract
The essential hydration and hardened properties of high sulfate resistance Portland cement paste/mortar were investigated with Al2(SO4)3 as admixture. Experiment results showed that that the addition of Al2(SO4)3 promoted the hydration of HSRP cement pastes, and the hydration rate accelerated with the increase of the addition amount. The mechanical properties and chloride diffusion coefficient of cement mortar were obviously improved with 0.25% Al2(SO4)3 addition . For instance, the compressive strength of AS0.25 cement mortars was 24.8% higher than AS0 samples and the chloride ion migration coefficient was 17.52% lower than AS0 samples after curing for 3-days.
