Density of Cement Sand and Aggregate in Kg/m3 | list of

Density of cement concrete. When cement is mixed with sand an aggregate is known as plain cement concrete. For concreting and RCC work like footing, column, beam and slab and for PCC work. Density of cement concrete is 2400 kg/m3, when it is measured in g/cm3,its density is 2.4 g/cm3, in lb/ft3 = 2400×0.0624= 150 lb/ft3 and in kN/m3 is 24.0.

Cement & Concrete Applications

Cement and Concrete Basics. In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
