Viscosity (apparent) as a function of grout type and concentration (Karol, 1983).

Viscosity (apparent) as a function of time (Littlejohn, 1985).
For Bingham fluids, there is a limiting radius to which grout can be pumped because of
the shear stress required to mobilize the grout. Littlejohn (1985) indicates that in soil this
can be estimated from:
