新型复合水泥助磨剂的研究

Study on new-type of composite cement grinding aids

通过对三种水泥助磨剂配制的新型复合水泥助磨剂的研究表明,新型复合水泥助磨剂可以将80 μm 筛余从9.4 %降低2.6 %-3.3 %,45μm 筛余从32 %降低到19 %-25 %;有利于提高3 d 强度和28 d 强度,且各项指标符合标准JC/T667-2004《水泥助磨剂》.

Based on the study of composite cement grinding aids formulated through three new cement grinding aids,the new type of composite cement grinding aids can reduce 80μm residue on sieve by from 9.4% to 2.6% ~ 3.3%, and45μm residue on sieve by from 32% to 19% ~ 25%, which is helpful to improve strength by3 d and 28 d, and various in-dexes can meet the standards of JC / T667-2004 'cement grinding aids'.
