Primjena betona od recikliranog agregata tijekom izgradnje nove zgrade dnevne bolnice u Zadru ; Construction of a new day hospital in Zadar using recycled aggregate concrete
U radu je prikazan pilot projekt primjene recikliranog agregata tijekom izgradnje nove zgrade dnevne bolnice OB Zadar. Projekt je uključivao rušenje postojeće bolnice i korištenje nastalog građevnog otpada kao recikliranog agregata u izgradnji dijela nove zgrade. Mehaničkom obradom nastalog otpada dobivena je frakcija 16/32 mm agregata te je on ispitan u skladu s normama HRN EN 206 i HRN EN 12620. Pripremljene su četiri mješavine betona i provedena ispitivanja svojstava u svježem stanju (konzistencija, gustoća, količina pora) i očvrsnulom stanju (tlačna čvrstoća, modul elastičnosti, kapilarno upijanje, vodonepropusnost, skupljanje uslijed sušenja). Ostvareni rezultati potvrđuju da se uzimanjem u obzir normi za reciklirani agregat te poznavanjem porijekla, za dane uvjete trajnosti može pripremiti beton svojstava istovrijednih običnom betonu. ; This paper presents the pilot project of application of recycled aggregate during construction of a new day hospital in Zadar. The project included the demolition of an existing hospital building and the use of generated construction waste as recycled aggregate in the construction of a part of the building. The 16/32 mm fraction of aggregate was obtained by mechanical processing of the generated waste which was then tested in accordance with the HRN EN 206 and HRN EN 12620 standards. Four concrete mixes were prepared, and the fresh (slump, density, air content) and hardened properties were tested (compressive strength, modulus of elasticity, capillary absorption, water permeability, drying shrinkage). The obtained results confirm that by complying with the standards for recycled aggregates and knowing their origin it is possible to produce concrete with properties equivalent to those of ordinary concrete for specified durability conditions.
