  • 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].
