Durability of beams with hybrid reinforcement from metal and basalt fiber reinforced polymer (BFRP) armature

Abstract: The article presents the program and the results of experimental tests of beam samples with metal, basalt fiber reinforced polymer (BFRP) and hybrid (metal and BFRP) reinforcement. The samples were made of standard concrete with quartz sand as the fine aggregate and concrete with fine fraction wastes of a mining and beneficiation complex (MBC) used instead of the sand. Short-run tests of the beams under monotonous static loading until destruction enabled the conclusion that durability of the BFRP reinforced be… Show more

“…Одним із недоліків BFRP арматури є в 3-4 рази менший модуль пружності на розтяг, ніж у металевої арматури. Існуючи експериментальні відомості роботи елементів, що згинаються, армованих BFRP арматурою вказують на те, що їх прогини перевищують прогини аналогічних зразків балок армованих металевою арматурою на 30-110% [5][6][7][8], а ширина розкриття тріщин більшою на 40-90% за експлуатаційного рівня навантажень [9,10]. Такі показники деформативності характерні всім композитним видам арматури за виключенням вуглецевої (CFRP).…”
