Cement 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.

The absolute volume of a concrete mix can be determined if the weight and bulk specific gravity of the components are known. For a concrete mix with 90-lbs of coarse aggregate with Gs = 2.65, 60-lbs of fine aggregate with Gs = 2.63, 25-lbs of cement, and 12-lbs of water the absolute volume is computed as follows: CA = 90 lb / (2.65 x 62.4 lb/cu
