Pump ability of concrete mixture improvement based on rich mortar theory testing method

摘要

Ready-mixed concrete has gained more and more popularity in the construction projects in China. Long distance or high dislocation pump of concrete mixture is difficult to control the concrete quality, even more worse, the concrete may become drier or stocked during the pumping. How to improve the concrete's pump ability is a major concern of the construction company. With the development of civil engineering, the building get much more higher and the bridge get much more longer, the pump ability of concrete matters the final product quality of the structure. This article proposed a comprehensive research on pump-ability of concrete mixture from the in field experiences by CCEED (China Construction Eighth Engineering Division).
