Effects of electric arc furnace dust on susceptibility of steel to corrosion in chloride-contaminated concrete

► Chloride-induced corrosion of steel in concrete is highly temperature-dependent. ► Crevices enhance susceptibility of steel in concrete to chloride-induced corrosion. ► Crevice corrosion in EAFD-free mortars occurred at low critical chloride contents. ► In mortars with small additions of EAFD this occurred at higher chloride contents.
