Testing Fresh Concrete at Point of Delivery

the slump of concrete be determined at the point of placement rather than at the point of delivery. For example, pumped concrete is often speci-fied to have slump measured at the end of the pumpline to preclude problems encountered with varying slump loss during pumping. This would provide for a slump higher than 4 in. at the point

Concrete Pumping - How to Pump Cement - Concrete Network

Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
