主　　题：chloride penetration chloride binding capacity pore structure steam curing cementitious materials 

摘      要：The resistance to chloride penetration of cement-based material with different curing regimes was investigated by solution titration,XRD,LF-NMR and rapid chloride migration *** results show that the curing regime has influences on the types and structure of the hydration products,which in turn affects their ability to bind chloride *** binding capacity of cementitious materials to chloride ions,porosity and chloride ion migration coefficient increased with the increase of water-cement ratio,while steam curing increased the porosity and chloride ion migration coefficient at the same time as it increased the chloride ion binding capacity of the *** lower water-cement ratios,the effect of steam curing on the resistance of cementitious materials to chloride ingress is negligible.
