氨基磺酸系高效减水剂应用性能研究

Research into the Applied Porformance of Aminosulphonic acid-based Super-dehydrate agent

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,而且与水泥具有很好的适应性,与萘系减水剂具有很好的相容性。

The paper studies the effect of adminosulphonic acid-based super-dehydrate agent（ASP） on the fluidity of cement paste,and the hardend and mechanical performance of the fresh concrete,as well as the dehyerate rate of ASP,the adaptability of ASP on cement,and the complex performance of ASP and naphthalene-based dehyerate agent.Test result indicates that in comparison with naphthalene-based dehyerate agent,ASP has the characteristics of low mixing ratio,high dehydrat rate,and the ability to restrain the slumped loss,and also has excellent adaptability with cement and good compatibility with naphthalene-based dehydrate agent.
