"Although the research, production and application of concrete admixtures in our country have made remarkable achievements, there are still many problems." Sun Zhenping pointed out that polycarboxylic acid superplasticizers are used to improve the workability (fluidity, cohesion and water retention) of concrete mixes, and people are also very concerned about its air induction, its impact on the setting time of concrete, and its impact on the mechanical properties, deformation and durability indicators of hardened concrete. Not only that, the description of the state of the concrete mix in the engineering community is also thin, thick, viscous, flowing, scraping the bottom, as well as sticky but not flowing, viscous and flowing, thin but not moving, thin and flowing, green light, rough, etc. These phenomena are not only related to the quality and characteristics of other raw materials of concrete, but also related to the polycarboxylic acid water-reducing agent used. In the concrete ind…
