Concrete pump pressure

Commonly used washing methods for concrete pumps

Nov 05, 2021 · Commonly used washing methods for concrete pumps (1) After pumping the concrete, reverse the pump for 1 to 2 cycles to eliminate the pressure in the conveying pipe. If pumping upwards, close the shut-off valve first to prevent backflow of concrete, and then remove the discharge pipe.

Assessment and prediction of concrete flow and pumping

Mar 01, 2020 · Concrete flow in a pipeline is a complex material response to the induced pressure accompanied by shear in LL [], friction between solid particles and pipe wall [10,18,19], and significant hydrodynamic interactions among particles within the partially sheared concrete bulk [20,21]; cf. Fig. 2.The extent to which frictional resistance is active depends on the state of saturation of the concrete

what kind of PSI does it take to move - Concrete Pumping

Apr 21, 2007 · the psi it takes to move concrete thru any boom or pipe depends the diameter of the pipe and the slump of the concrete, the smaller the pipe and the stiffer the mud the more psi the wetter the mud the less psi, the pressure on the the pumps max out at 320 bar. my A.C.P.A book is in my truck i see if i can get more specfic info. eugene.

Concrete Pumps - Types and Selection - The Constructor

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.
