Concrete made with recycled construction and demolition waste

U 21. stoljeću termin održivi razvoj se primjenjuje u svim granama ljudskog djelovanja, pa tako i u građevinskoj industriji. Recikliranje, ušteda energije, smanjenje emisije CO2 plinova su glavne teme današnjice. Građevinsku industriju, kao jednu od najvećih zagađivača CO2 plinom i jednog od najvećih generatora otpada, direktivama, poticajima se stimulira prema održivom razvoju. Jedan od najboljih načina je proizvodnja agregata od recikliranog građevnog otpada. Recikliranje se može izvoditi direktno na rušilištu i u automatiziranim postrojenjima. Uz pomoć grafova i objašnjenja prikazano je kakva su svojstva recikliranog agregata i kakva su svojstva samog betona s obzirom na udio recikliranog agregata. U radu se autor osvrće na stanje u gospodarenju i recikliranju građevnog otpada u Republici Hrvatskoj, kao i inovativnim, polivalentnim, energetski učinkovitim „ECO-SANDWICH“ zidnim panelima koji su proizvedeni i patentirani u Republici Hrvatskoj.In the 21st century, the term sustainable development is applied in all branches of human activity, including the construction industry. Recycling, energy saving, reducing CO2 emissions are the main topics. The construction industry, as one of the largest polluters of CO2 gas and one of the largest waste generators, is stimulated by directives and incentives towards sustainable development. One of the best ways is to produce aggregate - from construction demolition waste. Recycling can be performed directly on the demolition site and in automated plants. With the help of graphs and explanations, it is shown what are the properties of recycled aggregate and what are the properties of concrete itself with part of recycled aggregate. The paper discusses the situation in the management and recycling of construction waste in the Republic of Croatia, as well as innovative, polyvalent, energy efficient "ECO-SANDWICH ”wall panels that are manufactured and patented in the Republic of Croatia
