How to Calculate Density of Concrete

Feb 26, 2018  Wikipedia defines the density of a substance as: “its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: ρ = m / V”. Density is thus the necessary information to look for in the product data sheet to calculate the ...

density (p) = mass (m) ÷ volume (V) The density of concrete is 3.15 g/cm 3 while the density of aggregate will vary by the type of stone used. For instance, gravel has a much higher density than vermiculite. The density of a typical concrete mix is 2.4 g/cm 3 or 150 lbs/ft 3. Different mixes of concrete will use more or less aggregate as well.

slab - weight

Sep 15, 2015  The weight of a concrete slab can be estimated by computing the volume of the slab and multiplying the volume (V) by the density of the concrete. The volume is simply the area (A = L*W) times the depth (D). The formula for the weight of a slab used in this calculator is: TW = L•W•D•mD.

The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate. I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand.
