Chloride Consolidation and Penetration Behavior in Harden Mortar of Gangue Added Cement
This experimental research was to investigate the chloride penetration and consolidation behavior of OPC and coal gangue added cement. By comparing the results of two kinds of cement, results showed that the chloride consolidation of gangue added cement is higher than OPC. The chloride consolidation increased with more gangue added. The coal gangue is helpful to impede the chloride ingress until the added content reach 30%. The more gangue content decreased the fluid of mortar. And this increased the porosity of harden pastes. Furthermore the corrosion behavior of steel bar in OPC and G30 samples were conducted. Corrosion potential of gangue added cement moved positively comparing with OPC. These indicated that the propriety gangue content was helpful to steel bar protection.
