Density of dry concrete
WebTo find the formula for density, divide the formula of unit weight by gravitational constant g (acceleration due to gravity). But instead of having g in the formula, use the density of water replacing the unit weight of water. Basic formula for density (note: m = W/g) ρ = m V The following formulas are taken from unit weights of soil: WebMar 21, 2024 · The apparent density values are shown in Table 2, and the samples had an apparent density of 214~294 kg/m 3. The density of the reference sample without added fibers was greater than that of the sample with added fibers.
