摘要：
The slice-weighing method was used to investigate the unsaturated water transport of different cement pastes.The experimental results show that a sharp wetting front existed during water transport,the transport can be described by a non-linear diffusion equation,and transport coefficient of different materials exhibit various rules with water content of materials.The addition of fly-ash decreases transport coefficient of cement pastes in all the various water contents,even changes the transport mechanism.
