High Density Concrete: Types and Properties Concrete ...

As the name suggests, the density of this concrete varies from 3360 kg/m 3 to 3840 kg/m 3, whereas the density of normal concrete is of the order of 2400 kg/m 3. The density of light weight concrete is about 1900 kg/m 3 and that of normal concrete about 2400 kg/m 3. Thus the density of high density concrete is about 50% more than the density of ...

High Density Concrete The Construction Civil

High Density Concrete. High density concrete is a concrete having a density in the range of 6000 to 6400 kg/cu.m. High density concrete is also known as Heavy weight concrete. High density concrete is mainly used for the purpose of radiation shielding, for counterweights and other uses where high density is required. The high density concrete has a better shielding property, so that it can ...
