The dosage rate of NRG will depend on the fineness and the reagglomeration characteristics of each cement. Typical dosage rates will vary from 0.02% - 0.06% by weight of cement for Types I & II cements and from 0.04% - 0.08% by weight of cement for Type III cements. The optimum dosage rate must be determined during full scale cement mill tests.
we have been working on some high-impact, cutting-edge grinding aid formulations catering to custom needs of our customers. We were asked by this Cement Group to demonstrate the impact on 1-day strength by using one of our newly developed Grinding Aid formulation at this plant of theirs. The trials were conducted at plant-scale. Provided below ...
The action of additives in cement is divided into two types: Grinding aids; Quality improvers; In the world practice of cement grinding and other solids, for more than 60 years, the theory "Adsorption-related strength decrease of solids" has dominated, this theory is formulated in 1928 by Soviet scientist Peter Alexandrovich Rehbinder.
