摘要
减缩型聚羧酸系减水剂已是国内外研究的一个热点,它除了具有优异的分散性能外,还具有降低硬化混凝土收缩、保坍能力强等功能。主要总结了减缩型聚羧酸系减水剂的研究现状,包括国内外的研究进展和发展现状,并分析了减缩型聚羧酸系减水剂的减缩机理。
Multifimctional polycarboxylate superplasticizers has become a research hotspot, which in addition to imparting excellent dispersion properties, and some can reduce the shrinkage Of hardened concrete and render good slump retention of flesh concrete.The research status of shrinkage-reducing polycarboxylate superplasticizers, including the research progress at home and abroad and development present condition, and analyzes the mechanism of shrinkage-reducing polycarboxylate superplasticizers.
