Estimation of the Pumping Pressure from Concrete

Burj Khalifa – a new high for high-performance concrete

May 02, 2010 · The general trend of increasing pumping pressure with elevation and the effect of different concrete types are shown in Figure 6. At floor 101, the concrete for the core walls changed from C80-20 to C80-14, with a noticeable reduction in pumping pressure.

Solved Professor Giljum is working on a design project to

Professor Giljum is working on a design project to rehabilitate a damaged 54-in diameter reinforced concrete force main (i.e. pressure sewer). A pumping plant discharges to both the 54- in force main and a parallel 60-in relief force main, which combine at three different points in the system. Briefly explain how to estimate what percentage of

Parameters influencing pressure during pumping of self

Jul 27, 2012 · The lubrication layer facilitates the pumping of concrete through pipes. If no lubrication layer could be formed, the pumping pressure would be significantly higher to pump the concrete at the same discharge rate. Some authors take the effect of the lubrication layer into account by introducing a slipping or sliding velocity [18, 19, 24, 30, 31].
