Possibilities and Examples of Waste Utilization in Concrete : Master's Thesis

Abstract

Građevinarstvo stvara velike količine otpada, što zahtijeva učinkovito gospodarenje. Recikliranje građevinskog otpada je ključno za očuvanje resursa i smanjenje zagađenja. Beton je najprodavaniji građevinski materijal na svijetu. Povećana proizvodnja betona utječe na prirodne resurse, okoliš i zahtijeva velike količine energije. Jedan je od najviše korištenih građevinskih materijala, a pokazao se i kao medij u kojeg je moguće ugraditi razne vrste otpada poput industrijskog otpada, reciklirane plastike, recikliranog stakla, otpadnog tekstila i drugih. Proizvodnja cementa stvara visoke količine ugljičnog dioksida, troše se velike količine sirovina te nastaje velika količina otpada. U ovom radu prikazani su neki od recikliranih materijala, njihova svojstva te njihov utjecaj na mehanička svojstva betona i na svojstva svježe betonske mješavine.Construction generates large amounts of waste, requiring efficient management. Recycling construction waste is crucial for conserving resources and reducing pollution. Concrete is the most sold construction material in the world. Increased concrete production affects natural resources, and the environment, and requires large amounts of energy. It is one of the most used construction materials and has proven to be a medium into which various types of waste such as industrial waste, recycled plastic, recycled glass, waste textiles, and others can be incorporated. Cement production generates high amounts of carbon dioxide, large amounts of raw materials are consumed and consequently a large amount of waste is generated. This master's thesis presents some of the recycled materials, their properties, and their impact on the mechanical properties of concrete and the properties of fresh concrete mix
