Density of Different Construction Materials
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/ft3Density Values of Different Construction Materials
If two different materials are same in weight, but their density of both may be different. Lower dense material occupies more volume than higher dense material. Density also decides the sinking property of material. It is decided by knowing the density of liquid. If the material has lower density than liquid, then it will float on the surface of liquid. If it is more density than liquid, it will sink. For example water has a density of 1000kg/m3 , if we place bamboo wood (350kg/m3) on water it will float on water surface similarly if we drop a brick (1700 kg.m3) it will sink into the water. Density value of construction material will also help to find out the quantity of material needed for particular space.Unit weight or density of different construction materials are tabulated below.
