Applications of High Density Concrete in Preventing the ...

Zainab S. Al-Khafaji and Mayadah W. Falah Abstract. High Density Concrete is a concrete that produced to have density more than 2600 kg/m3. And the high density concrete prepared by the same materials like the normal concrete with little difference which is the high weight and low water cement ratio as well as less workability.

Concrete Density - an overview ScienceDirect Topics

The high density of such concrete is achieved by using high-density aggregates, and mostly these are natural materials, especially barytes, but also magnetite, haematite and other forms of iron ore. Concrete densities in excess of 3500 kg/m 3 can be achieved with barytes, but according to Neville 100 barytes concrete is not resistant to weathering.
