摘要: Abstract: The main hypothesis of the presented study is that negative effect phosphorus leaching from a green roof substrate can be reduced by including P-reactive material in drainage layer. In this work, different aggregates (Pollytag ® , lightweight expanded clay aggregates, chalcedony, serpentynite and crushed autoclaved aerated concrete) to used as layer are described. Physical parameters, e.g., granulometric composition, water absorption, bulk density porosity assessed. A sorption isotherm kinetic test were performed. chemical characteristics materials base for choosing best media P-removal efficiency concrete was confirmed column experiment. Adding implementation during construction reduce on runoff quality. Keywords: phosphorus; roof; substrate; aggregates; Pollytag
