Determination and Analysis of the Difference in the Setting Time of the Polycarboxylate-Type Efficient Retarding and Water Reducing Agent
In recent years,the requirements of engineering construction design for concrete are getting higher and higher,the country supports the development of green building materials,concrete admixtures are used more and more widely,and the output proportion of the polycarboxylate-type efficient retarding and water reducing agent in concrete admixtures has increased year by year because of its high water-reducing rate,good slump retention per-formance,low mixing amount and low costs.Therefore,in order to improve the overall quality of construction projects,the various properties of admixtures should be accurately measured,and the accurate determination of the difference in the setting time of concrete admixtures will affect the quality control of additive manufacturers,and the production,transportation and construction of ready-mixed concrete.Through the determination and analysis of the difference in the setting time of a polycarboxylate-type efficient retarding and water reducing agent,the analysis of influencing factors,precautions and results is put forward,so as to provide reference for the detection and analysis of the difference in the setting time of concrete admixtures.
