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 …
Addition Rates. The dosage rate of DARAGRIND® can vary from 0.005% to 0.1% by weight. The optimum dosage rate will depend on the fineness and the re-agglomeration characteristics of each material.
MA.G.A./C may be successfully utilized in all cases of pack-set phenomena (not due to humidity) inside the mills, particularly in the grinding of Portland and limestone cements. Production increases generally vary between 10% and 30%, depending on the fineness of the cement, on the grinding system available, on the clinker mineralogical composition, …
The repose angle, collapse angle, and compression degree of cement clinker changed significantly after adding grinding aid. After adding the No. 1 grinding aid, the strength of cement mortar increases. When the dosage is 0.035%, its strength increases significantly. Compared with the control group, it increases by about 10Mpa.
