文摘In this paper,internal relative humidity(IRH)of concrete with different W/C ratios under different curing conditions at early ages are studied by testing IRH change of concrete.Its results indicate,under no-curing condition,the IRH reduction of concrete is mainly dependent on moisture diffusion as well as self-desiccation.With the reduction of W/C ratio,the effect of moisture diffusion on IRH reduces,the effect of self-desiccation increases, and meanwhile,the reduction of lRH at different ages increases.After water curing for 28 days,the reduction of IRH with different W/C ratio is mainly dependent on moisture diffusion,and its declining trend is obviously affected by W/C ratios.
