Abstract

Disclosed is a method for testing the self-drying effect of a cement-based material, capable of testing the change in humidity of the cement-based material after the final setting until the Id stage of adding water, so as to reflect the water consumption therein and the self-drying course. In the time period after the final setting of the cement-based material until the 1 d stage of adding water and forming, the dew-point temperature inside the cement-based material is tested, and then the relative humidity inside the cement-based material is calculated using a formula. The present invention can test the change in humidity of the cement-based material after the final setting until the Id stage of adding water, so as to reflect the internal water consumption therein and the self-drying course. Further provided is a multi-stage test method for the whole course, capable of testing the whole course of continuous reduction in relative humidity from an initial 100%, in sealed conditions, starting with adding water and formation of the cement-based material, so as to provide a theoretical foundation for the quantitative calculation of the self-drying and shrinking thereof.
