EFFECT OF DIFFERENT TEMPERATURES ON THE SELF-COMPACTING CONCRETE CYLINDERS CONFINED WITH BFRP SHEETS, THE RESULTS - PART B

EFFECT OF DIFFERENT TEMPERATURES ON THE SELF-COMPACTING CONCRETE CYLINDERS CONFINED WITH BFRP SHEETS, THE RESULTS - PART B

Basalt Fiber reinforced polymer (BFRP) composites have drawn important attention in strengthening existing structures since the ordinary strengthening methods have many limits in terms of durability, self-weight and complex installation process. This paper investigates an extensive study of the effect of exposure to elevated heating regimes on the compressive strength of 21 unconfined and 21 confined concrete cylinders. For 1, 2, and 3 hours, all cylinders were subjected to heating regimes of 100°C and 300°C. The compressive strengths of unwrapped concrete cylinders were compared to wrapped cylinders' counterparts. The extreme temperatures used in the current investigation had essentially minor influence on the compressive strength of the BFRP wrapped cylinders. however, the unconfined specimens had high affected. When the exposure hours and heating regimes level increased, the compressive strength of the unconfined cylinders dropped. The highest compressive strength in unconfined specimens loss were measured to be 36.71 % after 3 hours of exposure to 300°C.
