Possible application of self-compacting concrete
Mogućnost primene samozbijajućeg betona
Apstrakt
The results of laboratory testing of self-compacting concrete (SCC) made with a new-generation superplasticizer are presented in this paper. The testing was performed both in normal curing conditions (specimens cured in water with temperature 20±2°C), as well as using accelerated hardening regime - steaming (inside the heating chamber at 70°C). The density and technological parameters of the fresh concrete ("Slump-flow Test" and "L-box Test") were measured first, and later (after 8h, 24h, 7 days and 28 days) the density of the hardened concrete as well as the compressive strength were measured. The obtained results show undoubtedly that the tested self-compacting concrete may be successfully applied in the process of precasting of concrete elements.
U radu se prikazuju rezultati ispitivanja samozbijajućeg betona (Self Compacting Concrete) spravljenog sa superplastifikatorom najnovije generacije, kako u uslovima normalnog očvršćavanja (u vodi temperature 20±2°C), tako i u režimu ubrzanog očvršćavanja putem zaparivanja (u klima komori na temperaturi 70°C). Na svežem betonu ispitivane su zapreminska masa i parametri tehnologičnosti mešavine ("Slump-flow Test" i "L-boh Test"), dok su na očvrslom betonu ispitivane zapreminska masa i čvrstoća pri pritisku (na 8h, 24h, 7 dana i 28 dana). Dobijem rezultati nedvosmisleno pokazuju da se predmetni samozbijajući beton može veoma uspešno primeniti u procesu prefabrikacije betonskih elemenata.
