氨基磺酸系高效减水剂应用性能研究

Application Performance of Aminosulphonic Acid-based Superplasticizer

研究了氨基磺酸系高效减水剂(ASP)对水泥净浆流动度、新拌砼硬化性能及力学性能的影响以及ASP减水率、ASP与水泥适应性、ASP与萘系减水剂复合性能。试验表明,ASP与萘系减水剂相比,具有低掺量、高减水率以及控制坍落度损失的功能,而且与水泥有很好的适应性,与萘系减水剂有很好的相容性。

The effects of aminosulphonic acid-based superplasticizer（ASP）on the fluidity of cement paste and harden perfomance and mechanical performance of fresh concrete were studied. The water reducing rate, adaptation to cements and eompatibility with naphthalene-based water reducer of ASP were tested. Teating results indicate that in comparison with naphthalene-based water reducer, ASP has the characteristics of low cost, highly effective water reducing ability and the ability restraining slump loss, and also has excellent adaptation to cements and good compatibili- ty with naphthalime-based water redueer.
