The article discusses the possibility of utilising both wastes from CHP plants (Combined heat and power plants), i.e. fly ash, and PET plastic waste (polyethylene terephthalate), through pro-cessing into lightweight aggregate used construct reinforced concrete beam elements to protect the natural environment. Properties of the utilised lightweight artificial aggregates are presented. Selected results of experimental tests in load-bearing capacity and deformability of reinforced concrete beams made in the model scale are presented. An analysis of the test showed that, despite their lower resis-tance to crushing, artificial aggregate beam elements have the same load-bearing capacity as rein-forced concrete beams made with recycled aggregate, with better flexural strength properties in some cases.

W artykule omówiono możliwości utylizacji zarówno odpadów z elektrociepłowni, tj. popiołów lotnych, jak i odpadów tworzyw sztucznych PET (politereftalan etylenu), poprzez przetworzenie na lekkie kruszywo wykorzystywane do konstruowania żelbetowych elementów belkowych w celu ochrony środowiska naturalnego. Przedstawiono właściwości zastosowanych lekkich kruszyw sztucznych. Omówiono wybrane wyniki badań eksperymentalnych w zakresie nośności i odkształcalności belek żelbetowych wykonanych w skali modelowej. Analiza badań wykazała, że elementy belkowe wykonane z zastosowaniem kruszywa sztucznego, pomimo niższej wytrzymałości kruszywa na zgniatanie, nie różnią się pod względem nośności od belek żelbetowych wykonanych z kruszywa recyklingowego, w niektórych przypadkach mają wyższą wytrzymałość na zginanie.
