Graded from 0.5mm to 5mm.
Approximately 4.5 tonnes per m3
( 4.5gm per cm3
Description & Application:
Steel punchings (perforations) suitable for the manufacture of counter-weight concrete and setting in resin for marine ballast.
Heavyweight steel aggregate behaves in a similar way to "normal" sharp sand when used in a concrete mix. However, whilst similar water/cement ratios should be used, the weight of cement in a mix will be significantly reduced due to the density of the aggregate.
"Normal" concretes using natural sand aggregates may be assumed to have a cured density in the order of 2.4 tonnes per m3
a well compacted steel aggregate concrete is likely to achieve a density approximately double this figure.
