| Abstract: | This paper research the effect of shrinkage reducing agent on every performance such as the strength, the process of dry shrinkage and hydration and pore structure etc of the cement based materials, and has carried on initial analysis to the function mechanism of shrinkage reducing agent. Mixing shrinkage reducing agent can reduce the surface tension of hole liquid, consequently make the negative pressure of capillary tube depress, thus suppress the shrink effectively. |
