The papers presents the results of monitoring of various heavy metals leaching from concrete samples based on ordinary CEM I Portland cement without any additives and with silica fume exposed to the sulphate environments. The leaching experiments of compact cement composites proceeded during 180-day period in various aggressive and reference media (H2SO4, MgSO4, fresh water). The concentrations of manganese (Mn), iron (Fe), copper (Cu) and cobalt (Co) ions in liquid media were measured. Only a small part of total metal content was extracted from concrete samples into the liquid media (up to 17% for manganese and 0.3% for iron). Concrete samples with microsilica were found to have better performance in terms of leaching of Mn, Fe, Co and Cu ions than samples without microsilica. The most significant effect of sulphuric acid as aggressive environment causing analyzed metals releasing was confirmed.

Keywords: Cement; concrete; leaching; heavy metals.
