Phosphorous enters the clinker minerals and negatively affects the phase composition clinker, and thus the quality of cement. In environmental point of view, phosphates coming into the water cause the eutrophication processes. The environmental criteria including phosphorous content for materials and products are stated assessment of type I which determines is the most used evaluation process in Slovak Republic. Cements are one of the building product groups for which the required criteria are stated and the national eco-label is possible to obtain. Cements supplied on the market must fulfil the basic requirements stated by technical norms and regulations in order to achieve certain properties in concrete and human safety. Cements environmental criteria within the certification process include requirements for limit value of phosphorous (less than 3% of P2O5). The content of phosphorous expressed as P2O5 was in all measured cement samples less than stated limit in eco-labelling process.
