Experimental Observation on Variation of Rheological Properties during Concrete Pumping

International Journal of Concrete Structures and Materials, 2018
Workability of concrete varies during pumping. Even though concrete satisfies the required workability before pumping, it often does not satisfy the required standard after pumping. Moreover, serious problem could happen such as segregation and blockage.
