Pumping Theory on Crushed Sand Concrete
Abstract
Based on force analysis on pump concrete and push facility, quantitative relation between pump resistance and pressure of pipe wall is given. Based on Bingham model, the relationship among pump resistance, yield stress and plastic viscosity is derived out. During pumping, concrete segregating or not can be forecast by testing pumping resistance.
