Pumping agent: concrete mixture can improve the pumping performance of admixtures called pumping agent. The so-called pumping performance, with a concrete mixture is smooth through the pipeline, not blocking, not segregation, viscoplastic good performance. Pumping the water reducing agent composite, retarders, air entraining agent, drag reducing agents made. Pumping agent performance: high fluidized cohesive, lubrication, retarding effect, suitable for the production of high-strength concrete or flow pattern type. Pumping agent http://www.lygqjc.com/
