Comparative analysis of selected features of traditional and photocatalytical paving stones

Abstract

Nature friendly technologies in today’s world are the subject of scientific research and the interest of local authorities and the residents themselves. In the context of the city, one of the most important issues is the neutralization of air pollution generated by transport and heating of the premises with the use of solid fuels. The article analyses differences of the response of traditional and photocatalytic paving stones. We analysed water absorption, frost resistance, tensile strength at splitting and abrasion of paving stones. It has been proved that paving stones exposed to atmospheric factors and pollution during one heating season met the assumed quality criteria. In addition, the results obtained for the characteristics analysed were higher than the results of samples tested in laboratory conditions. The results also indicate a slight advantage of photocatalytic cubes in terms of their resistance to abrasion and tensile strength at splitting. Traditional and photocatalytic paving stones withstand well the operating conditions. It seems that products based on TioCem® cement are the future implementation of pedestrian and traffic routes.
