Abstract
Samozbijajući beton je materijal visoke sposobnosti tečenja koji bez dodatnog vibriranja popunjava oplatu, a njegov nedostatak su visoki troškovi. S druge strane javlja se sve veća potreba za očuvanjem okoliša i uporabom obnovljivih izvora energije. Brojna istraživanja u području građevinarstva nastoje pronaći moguću primjenu biomase i pepela nastalog njenim spaljivanjem. U ovom radu ispitana je moguća upotreba pepela ljuski suncokretovih sjemenki kao zamjene za udio kamenog brašna u samozbijajućem betonu. U tu svrhu izrađene su četiri betonske mješavine, te ispitane u svježem i očvrslom stanju. Prema rezultatima utvrđeno je da pepeo ljuski suncokretovih sjemenki smanjuje mehanička svojstva betona, a u svježem stanju produžuje vrijeme razastiranja. Ostala svojstva ovise o omjerima i vrstama dodataka. Dobiveni rezultati ne ukazuju na to da pepeo ljuski suncokretovih sjemenki ima pucolanska svojstva.
Abstract (english)
Self-compacting concrete is a high-flow material that fills the formwork without additional vibration, and its main disadvantage is high cost. On the other hand, there is a growing need for environmental protection and the use of renewable energy. Numerous researches are trying to find a possible use of biomass and biomass ashes in civil engineering. This study examines the possible use of sunflower seed shells ash as a substitute for the proportion of stone powder in self-compacting concrete. For this purpose, four concrete mixtures were made and tested in a fresh and hardened state. According to the results, the sunflower seed shells ash reduces the mechanical properties of the concrete and in the fresh state prolongs the setting time. Other properties depend on the ratios and types of powders. The obtained results do not indicate that sunflower seed shells ash has pozzolanic activity.
