In many concrete engineering projects, traditional high-efficiency concrete such as naphthalene series cannot meet the engineering needs due to the limitations of technical performance. The new generation of water reducing agents, polycarboxylate based high-performance water reducing agents, which have attracted much attention both domestically and internationally, have achieved effective molecular structure design based on the mechanism of dispersed cement. They have a super dispersed type and can prevent concrete slump loss without causing significant retardation. They have a high plasticizing effect at low dosages, good fluidity retention, large degree of freedom for cement to adapt to wide molecular structures, multiple synthesis technologies, and large room for high-performance development. They have significant reinforcement effects on concrete, can reduce concrete shrinkage, and have extremely low harmful substance content. These technical performance characteristics endow concr…
