Pumping agents are admixtures that can improve the pumping performance of concrete mixtures. The pumping agent has the characteristics of water reduction, retardation, enhancement, early strength, and is odorless and non-flammable. Pumping agents are becoming more and more widely used in the construction industry. They are a type of additive that must be added in the preparation and production process of ready-mixed concrete. Due to the special performance requirements of ready-mixed concrete, it cannot be achieved by cement or thick aggregates alone, and its performance must be improved by adding admixtures.
