Cements are one of the building product groups in Slovak republic for which the required criteria are stated and the national eco-label is possible to obtain. One of the criteria for an award eco-label for cements is the limitation of the occurrence of chromium (VI) in cements. The selected types of cements were assessed and average values of soluble chromium (VI) for each type of cements were compared to the requirement in Slovak eco-labeling process — 1.8 mg chromium (VI) per 1 kg of cement (1.8 ppm). The measured values of soluble chromium (VI) content in common used types of cements were higher than eco-labeling limit at almost of 60% of evaluated cements.
