Effect of Acid Environment on Bond Durability of Basalt Fiber Reinforced Polymer Bars and Steel Bars Embedded in Concrete
Bond durability of ribbed basalt fiber reinforced polymer bars and steel bars exposed to sulphuric acid environment for different durations was investigated. Seventy-two pull out specimens were tested under direct tensile load to study the bond performance in terms of their bond strength and bond failure modes. The test parameters included the bar material such as basalt and steel, the duration of exposure such as 28 and 56 days, grade of concrete such as M25, M30 and M35, and bar diameter such as 10, 12, 20 mm. Experimental results showed that the bond strength of BFRP bars to concrete decreased by 19% of that of steel bars. All the specimens failed by concrete splitting mode of failure. 28 days of acid conditioning increased the bond strength of BFRP specimens by 5.45–53.9% and for steel specimens by 1.93–28.73% of their initial strength. 56 days of acid conditioning decreased the bond strength of BFRP specimens by 1.33–24.86% and for steel specimens by 8.78–18.44% of their initial strength.
