Abstract
The effect of aluminium sulfate on cement properties was studied systematically and the mechanism was analyzed using XRD and SEM tests. Experimental results showed that the addition of aluminium sulfate will shorten the setting time of cement, increase the drying shrinkage and improve the early strength; however it will weaken the late strength of cement and reduce the fluidity. Micro-research showed that the addition of aluminium sulfate will change the morphology and location of aluminium sulfate distinctly.
