Effect of Curing Condition on Structure and Scaling Resistance of Specified Density Concrete


Article Preview

Influence of curing condition on internal relative humidity (IRH) of specified density concrete with different w/b ratios, pore structure of cement paste, hydrated product as well as scaling resistance of concrete were investigated. The results show that, as for concrete with w/b ratio of 0.31, water and standard curing can stop or slow up the migration of internal water, and the structure of cement paste is dense due to good hydrated environment, so the scaling resistance of concrete is best; as for concrete with w/b ratio of 0.47, the IRH of concrete under natural curing condition at 28 days is still 90%, there is sufficient water for the hydration of cement, and internal water content of concrete is lower as compared to concrete under water and standard curing conditions which makes it less easy to saturate, so natural curing concrete has better scaling resistance.
