摘要
采用不同工艺的合成方法,得到两种具有高分散作用的聚羧酸减水剂。通过对这两种减水剂的性能试验,结果表明本次所合成的减水剂具有较高的减水率、较好的坍落度保持性,并能大幅提高混凝土强度。
Two kinds of polycarboxylic plasticizer with high dispersion were synthesized through two various synthetic procedures.The result shows that the two super plasticizers have the following excellent properties： high fewer adding quantities,higher water-reducing ratio,better strengthening effects for concrete.
