Is the concrete electrically conductive and does this lead to a risk of electrical shock?
Typical steel fiber reinforced concrete contains less than 0.5% vol. steel fibers and hardly more than 0.75% vol. those fibers are discontinuous and not connected to each other. tests only show a slight decrease in electrical resistivity due to the addition of steel fibers. However, the resistance to current flow is still substantial. effects from moisture content and aggregate composition are much more dominant than the addition of steel fibers.
