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 of liquid without solids (lb/ft 3, kg/m 3)

Just as a reminder, it goes as follows: weight = volume × density. For clarity's sake, let's go through a quick example. Let's say we have 15 cubic meters of Portland concrete. The density of this type of concrete in kilograms per cubic meter is 2,300, so the calculation goes as follows: weight of concrete = 15 m³ × 2,300 kg/m³ = 34,500 kg.
