Abstract

In this study, the influence of lead sulfate on the transport of chloride in mortar was investigated by chloride ion permeation test. The changes of cement hydration products in cement-based materials containing lead sulfate were observed by scanning electron microscopy (SEM).The results show that the free chloride ions in the concrete decrease when the lead sulfate is added. Lead sulfate can also lead the formation of the ettringite,which can acclerate chloride transport.
