Abstract:
Concrete has been utilized in building for many decades because of the need for
reinforcements because of its fragile nature. Bamboo, wire mesh, and structural steel
have all been used to reinforce concrete during the last few decades. Regarding
commercial and subterranean applications of concrete-reinforced steel (CRS),
corrosion is more likely to occur. Rusted steel used in concrete rehabilitation is time-
consuming and expensive. GFRP, CFRP, and AFRP bars are just a few of the many
choices that researchers have advised thus far. Apart from the superior strength-to-
weight ratio and low corrosion susceptibility, these bars surpassed rebars in every other
regard. However, further research needs to be done to properly understand how the
BFRP bars respond to a variety of concrete mixtures. Basalt fiber reinforced polymer
bars (BFRP) is produced by mixing thin basalt fibers with resin to make a polymeric
matrix using the pultrusion method. Several variables, including the kind of concrete,
bar size, embedment length, and a variety of harsh environments, are being altered to
examine the bonding performance of BFRP bars. The pull-out performance of three
distinct bar diameters (12.7, 15.9, and 19mm) was investigated by adjusting three
different embedment lengths (5db, 10db, and 15db) in various concretes, including
normal strength, high strength, and geopolymer concrete. A seawater environment and
an alkaline environment were used to evaluate each scenario. Bond strengths of 22.5,
20.99, and 15.32 MPa were observed in high strength, normal strength, and geopolymer
concrete, respectively, tested in an environment that was under controlled conditions.
High strength, normal strength, and geopolymer concrete retained 82 percent, 79
percent, and 76 percent of their bond strength, respectively, in an alkaline environment.
When exposed to seawater, high strength, normal strength, and geopolymer concrete
showed bond strength retention of 80%, 76%, and 79%, respectively. The bond strength
of the BFRP bar was predicted using the Fib bulletin method for 50 years
