Durability of Alkali-Activated Slag Cement in Seawater Environment
The durability of alkali-activated slag mortar in seawater environment, compared with that of ordinary portland cement mortar, was studied by drying-wetting test in accelerated laboratory seawater. The drying-wetting resistance, porosity, performance mechanism, and depth of chloride ingress were analyzed. The results show the mechanical properties of the AAS mortars were improved after 40 cycles, opposite to that of the OPC mortar, which is mostly due to the difference of porosity and pore structure. The chloride penetration resistance of AAS mortar was better, comparing to conventional OPC mortar.
