| Abstract: | The influence of two kinds of grinding aids A and B on flowability, dispersed state of particles and performance of mortars were investigated. Mechanism of action of grinding aids was also discussed. The results show that the grinding aids improve the flowability, increase fineness of fine particles, and increase strength of 3d and 28d of cement mortar. No considerable change in blain specific surface was found in the study. The action and mechanism of grinding aids were also dicussed. |
