A comparison between properties of self-compacting concrete and normal concrete : Master's Thesis

U radu je prikazana usporedba svojstava samozbijajućeg i običnog vibriranog betona, pri čemu su se obje vrste betona radile sa istim sastavom uz izuzetak superplastifikatora kod vibriranog betona. Izrađeno je ukupno pet mješavina svake vrste betona koje su ispitane u svježem i očvrslom stanju. U svježem stanju samozbijajućem betonu je ispitana obradivost pomoću: razastiranja, T500, vremena tečenja, J-prstena, i L-kutije. Običnom betonu se u svježem stanju ispituje slijeganje, razastiranje i Vebe vrijeme. U očvrslom stanju je svim uzorcima određena tlačna čvrstoća nakon 7, 14 i 28 dana, dinamički modul elastičnosti te kapilarno upijane. Svi rezultati su analizirani i međusobno uspoređeni.This thesis covers comparison between self-compacting concrete and normal concrete. Both types of concrete were prepared using identical composition with the exception superplasticizer to the normal concrete. Five mixtures of each kind of concrete were prepared end tested in fresh and hardened state. The properties of the fresh self-compacting concrete were measured using slump flow, T500, V-fuel, J-ring and L-box methods. Normal concrete was tested using slump method, flow method and Vebe time. Dynamic module of elasticity and compressive strength were tested in the hardened state after 7, 14 and 28 days. All results were analyzed and compared
