The mechanisms of cement additives. Cement additives enhance the efficiency of the grinding process. The cement treated with these additives has a narrower particle size distribution (PSD). This narrower PSD impacts cement performance characteristics, including paste water demand, setting time, and strength development.
Pre-test 3: Wetting and Dispersing Additives with Grinding Resin and Let-down Systems In order to evaluate the compatibility, 5% active substance of deflocculating wetting and dispersing additive should be added to the grinding resin and also to the various non-pigmented let-down systems. There should be no turbidity,
Mechanisms of grinding modification by chemical additives: organic reagents @article{ElShall1984MechanismsOG, title={Mechanisms of grinding modification by chemical additives: organic reagents}, author={Hassan E. El-Shall and P. Somasundaran}, journal={Powder Technology}, year={1984}, volume={38}, pages={267-273} }
The above discussion suggests that the effect of chemical additives on the grinding process has been attributed to individual mechanism. However, grinding is an integral process involving several simultaneous sabprocesses such as transport of particles to and from the grinding zone, where they are subjected to different kinds of stresses.
