Pumped concrete - ScienceDirect

2003-1-1  Pressure is applied by a hydraulic pump to a piston acting directly on the concrete until an operating pressure of 3.5 N/mm 2 is achieved, replicating typical concrete pump hydraulic pressure of 390 kg/cm 2. A tap is opened and the volume of grout emitted under pressure is measured.

Estimation of the Pumping Pressure from Concrete ...

A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface friction between concrete and the wall of the pumping pipes. This friction is determined by the thickness and the rheology of the boundary layer formed at the interface.
