Slurry Density

2021-8-27 · Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 - c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l = density …

Particle Density

Particle density and bulk density are two basic ways to express sediment weight. Particle density is defined as the mass of a unit volume of sediment solids. A simple example is that if 1 cm 3 of solid material weighs 2.65 g, the particle density is 2.65 g/cm 3. Particle densities generally fall between 2.60 and 2.75 g/cm 3 for mineral particles.

In place density of 3/4 Crushed stone

 · If the 3/4" crushed stone has sufficient fines in it, a proctor curve can be obtained. We see it used extensively on projects. Ron is correct that nuclear density testing on clean rock is inaccurate at best. The choice between backscatter and direct transmission can be governed by the layer thickness.
