Abstract

Most materials in mining and civil engineering construction are not only viscoplastic, but also cohesive frictional. Fresh concrete, fly ash and mining slurries are all granular-frictional-visco-plastic fluids, although solid concrete is normally considered as a cohesive frictional material. As an introductory mathematical framework, this paper presents formulation for flow rate as a function of pressure and pressure gradient in pipes and discs.

Most materials in mining and civil engineering construction are not only viscoplastic, but also cohesive
frictional. Fresh concrete, fly ash and mining slurries are all granular-frictional-visco-plastic fluids, although solid
concrete is normally considered as a cohesive frictional material. As an introductory mathematical framework, this
paper presents formulation for flow rate as a function of pressure and pressure gradient in pipes and discs.
