The water absorption and desorption process of different prewetting degree ceramsites embedded in ceramsite concrete was obtained by a U-tube micro pressure measurement device. The internal relative humidities of ceramsite concrete using different prewetting degree ceramsites were monitored by humidity sensors. The study reveals that, with the increase of ceramsite prewetting degree, the internal relative humidity of ceramsite concrete increases because the reservoir function of ceramsite is more obvious.
