Weighing In on High-Density Concrete - NPCA

Apr 11, 2013  Why use high-density concrete? Most times, dense concrete is used for radiation shielding purposes, where the required thickness of walls made with normal concrete can be decreased and thereby provide more interior workspace. In the ’60s and ’70s, HD concrete was used quite a bit due to the boom in nuclear power plant construction.

Materials For High Density Concrete Production

To achieve the required concrete density to absorb the radiation a combination of high-density aggregates steel shot (fine aggregate) and hematite iron-ore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately R370.00 to R7 600.00 per cubic metre of concrete in 1996.
