Density of construction materials are its mass per unit volume of materials. It is expressed in kg/m3 or lb/ft3 and shows compactness of building material. Density is also called as unit weight of substance. It is represented by symbol called row (p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material.
Density is defined as the ratio of mass to volume. p = m/v Units = kg/m3 or lb/ft3 Conversion: 1 kg/m3 = 0.624 lb/ft3.
The approximate density of different construction materials are tabulated below.
| Material | Density (Kg/m3) | Density (lb/ft3) |
|---|---|---|
| Water | 1000 | 62.43 |
| Sand | 1600 to 1840 | 101.80 |
| Cement | 1440 | 89.80 |
| Aggregate | 2200 to 2400 | 135 to 150 |
| Brick | 1500-1800 | 93.64 to 112.30 |
| Stone | 2600 to 2800 | 160 to 175 |
| Cement Mortar | 2000 | 125.00 |
| Lime Mortar | 1760 | 109.80 |
| Plain Cement Concrete | 2400 | 149.80 |
| Reinforced Cement Concrete | 2200 to 2500 | 137 to 156 |
| Steel Reinforcement | 7850 | 490 |
| Wood | 300 to 900 | 18 to 56 |
