The effects were examined of the ABESON-TEA grinding aid on the properties of gypsum-free Portland cements. The influence of the grinding aid on apparent viscosity of cement pastes, the time course of the hydration reactions and the compressive strength was studied. It was found that for a given specific surface of the cement, there exists an optimum amount of the grinding aid which improves the strength characteristics of binders. |
