U radu su prikazani rezultati sopstvenih laboratorijskih ispitivanja na samozbijajućem betonu (SCC – self-compacting concrete) i mikroarmiranom samozbijajućem betonu (SFR-SCC – steel fiber reinforced self-compacting concrete) u očvrslom stanju. Upotrebljena su čelična vlakna sa kukicama na krajevima. Ispitan je doprinos zapreminskog sadržaja vlakana Vf i faktora oblika vlakana l/d na određena mehanička svojstva samozbijajućeg betona. Zapreminski sadržaj vlakana Vf u uzorcima je variran u sledećim vrednostima: 0,5%, 1,0%, 1,5% i 2,0%. Korišćena su čelična vlakna dužine 35 i 60mm pri čemu je faktor oblika vlakana iznosio 47 i 80. Ispitana su sledeća svojstva na očvrslom betonu: čvrstoća betona pri pritisku, čvrstoća pri zatezanju cepanjem i čvrstoća pri savijanju. Rezultati pokazuju da se sa povećanjem zapreminskog sadržaja vlakana Vf od 0,5% do 2,0% čvrstoća betona na zatezanje pri cepanju kao i čvrstoća pri savijanju takođe povećale u odnosu na kontrolne uzorke bez vlakana. Rezultati pokazuju da sa povećanjem faktor oblika vlakana l/d i za vrednosti Vf iznad 1,0% dolazi do pada čvrstoće betona pri pritisku.
