Abstract
Činjenica da je beton jedan od najkorištenijih materijala u svijetu i veliki razmjeri njegove proizvodnje otvaraju razna pitanja vezana uz utjecaj na okoliš i održivi razvoj. Glavni problemi su eksploatacija prirodnog kamena iz okoliša za proizvodnju betonskog agregata te odlaganje građevinskog otpada nastalog rušenjem. Potencijalno riješenje je ponovna upotreba građevinskog otpada nastalog rušenjem postojećih zgrada i infrastrukture, odnosno recikliranje betona s ciljem dobivanja recikliranog betonskog agregata i njegove upotrebe kao sekundarne sirovine. Trenutni problemi su pogoršana svojstva betona spravljenog recikliranim agregatom u odnosu na beton spravljen prirodnim agregatom, te nedovoljni broj istraživanja u ovom području. Ovaj rad daje teorijski pregled problematike ponovne upotrebe građevinskog otpada, prikazujući dosadašnja istraživanja i zaključke vezane uz beton od recikliranog agregata, te eksperimentalni dio u kojemu su ispitana određena svojstva betona spravljenog recikliranim agregatom s postotkom zamjene krupnog agregata recikliranim od 70%, uspoređujući ih sa svojstvima betona spravljenog prirodnim agregatom. Osim ispitivanja konzistencije svježe betonske smjese slijeganjem, ispitana su tlačna čvrstoća, otpornost na izlaganje ciklusima smrzavanja i odmrzavanja te otpornost na abraziju očvsnulih betonskih uzoraka. Beton od recikliranog agregata pokazao je, u odnosu na referentni beton, smanjenu tlačnu čvrstoću, bolju otpornost na izlaganje ciklusima smrzavanja i odmrzavanja te istu otpornost na abraziju.
Abstract (english)
The fact that concrete is one of the most used material in the world and the vast proportion of its production open a series of questions related to the environmental impact and sustainability issues. The main problems are the exploitation od natural stone material, extracted from the natural habitat to produce concrete aggregate and the disposal of construcion and demolition waste. The potential solution is to re-use demolition waste by concrete recycling in order to produce recycled aggregate as a secondary raw material. The related problems are the deterioraion of properties of recycled aggregate concrete compared to natural aggregate concrete, as well as the insufficient number of researches on this topic. This study shows a teoretical overview on the re-usal of construcion and demolition waste, by displaying the so-far researches and their conclusions, as well as the practical part in which the properties of concrete with 70% of sustitution with recycled aggregate were tested in comparison to natural aggregate concrete. Beside the slump test of the fresh concrete mixtures, the tested properties of hardened concrete were the compressive strength, the freeze-thaw ressistance and the abrasion resistance. The recycled aggregate concrete showed a lower compressive strenght, a better freeze-thaw ressistance and and equal abrasion ressistance.
