Investigating the possibility of obtaining ultra-light weight concrete usingpolyurethane waste and its performance in removing lead pollutants fromcontaminated water

The decomposition resistance of plastics against atmospheric conditions causes water, land and airpollution. Therefore, investigating the methods of reusing polymer products is of great importance.The ease of implementation and economic efficiency of mechanical recycling methods have attractedmore attention from industrialists. In this research, the performance of polyurethane waste aslightweight aggregates in concrete was investigated. By using these wastes, ultra-light concrete witha specific weight of ۸۴۵ kg/m۳ was obtained. Also, due to the permeability of this concrete, thepossibility of removing the chromium pollutant was investigated.
