ادامه مطلبDensity 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.
ادامه مطلبCement density:- generally density of cement is around 1440kg/m3 or it is measured in other unit- their density is 1.440 in g/cm3, 94 in lb/ft3 and 14.40 in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3 is density of cement.
ادامه مطلبDetermine the Density of Concrete. Density is the measure of mass for a given volume and is defined by the formula: 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 …
