Bond Performance of Near-Surface Mounted BFRP Bars to Concrete
Aljidda, Omar; El Refai, Ahmed; Alnahhal, Wael ( Qatar University Press , 2023 , Conference Paper)This paper presents the test results of a study on the bond performance of near-surface mounted (NSM) basalt fiber reinforced polymer (BFRP) bars to concrete. Twelve C-shape concrete specimens were tested under direct ... -
Bond performance of tensile lap-spliced basalt-FRP reinforcement in high-strength concrete beams
Eltantawi, Islam; Alnahhal, Wael; El Refai, Ahmed; Younis, Adel; Alnuaimi, Nasser; Kahraman, Ramazan... more authors ... less authors ( Elsevier , 2022 , Article)This paper investigates the bond between high-strength concrete (HSC) and tensile lap-spliced basalt fiber-reinforced polymer (BFRP) bars. Ten large-scale BFRP-reinforced concrete beams (300 x 450 x 3900 mm) were fabricated ... -
Effect of corrosion damage on the flexural performance of RC beams strengthened with FRCM composites
Elghazy, Mohammed; El Refai, Ahmed; Ebead, Usama; Nanni, Antonio ( Elsevier Ltd , 2017 , Article)This paper reports on the flexural behavior of corrosion-damaged reinforced concrete (RC) beams strengthened with different fabric-reinforced cementitious matrix (FRCM) composites. Three groups of beams were subjected to ... -
Effectiveness of Fabric-Reinforced Cementitious Matrix in Strengthening Reinforced Concrete Beams
Ebead, Usama; Shrestha, Kshitij C.; Afzal, Muhammad S.; El Refai, Ahmed ( American Society of Civil Engineers (ASCE) , 2017 , Article)This paper reports on the efficiency of fabric-reinforced cementitious matrix (FRCM) in enhancing the flexural capacity and deformational characteristics of RC beams. In the main experimental part of the paper, 12 RC beams, ... -
