AbstractThe composition and properties of raw materials have significant influences on water retention capacity of mortar, but the basic origin remains unclear. To clarify the movement of water inside mortar and the mechanism of water retention, the dynamic dewatering experiment was designed and the mathematical model describing the dewatering process of mortar was set up in this work. The model proved to be effective according to the results from dynamic dewatering experiment. The study demonstrated that capillary gradual contraction model is suitable for describing early dewatering process of fresh mortar and the parameters in the dewatering equation are relevant to the properties of raw materials, which certify that the model is of physical significance. Moreover, influencing factors such as water properties and binding materials properties were obtained and their relationship with water retention of mortar were discussed theoretically based on capillary gradual contraction model.
