Density of Building Materials

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/m 3  or lb/ft 3 Conversion: 1 kg/m 3  = 0.624 lb/ft 3 Density 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
