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 ... -
Enhancing the Bond Durability of Basalt Fiber Reinforced Polymer Bars Using Basalt-Macro Fiber Reinforced Concrete
Taha, Alaa; Alnahhal, Wael; Al Nuaimi, Nasser ( Qatar University Press , 2023 , Conference Paper)This paper presents a study about the bond durability of basalt fiber reinforced polymers (BFRP) bars embedded in concrete incorporating basalt macro fibers (BMF) when conditioned in harsh saline environment at 60 °C. A ... -
Experimental Investigation on the Flexural Capacity of Reinforced Concrete Beams with Treated Wastewater and Recycled Concrete Aggregates
Abushanab, Abdelrahman; Alnahhal, Wael ( Qatar University Press , 2023 , Conference Paper)Eco-friendly concrete is the most recommended sustainable option to reduce the excessive diminution of concrete natural resources and the high generation of greenhouse gas emissions. Therefore, the present study explores ... -
Parametric study on moment redistribution of fiber reinforced concrete continuous beams with basalt FRP bars
Abushanab, Abdelrahman Hamdi; Alnahhal, Wael I ( Qatar University Press , 2020 , Poster)The state of Qatar is suffering from its harsh environment and coastal conditions which stand for most of the year. As a result, steel-reinforced concrete structures are subjected to rapid corrosion and deterioration. ... -
Parametric study on moment redistribution of fiber reinforced concrete continuous beams with basalt FRP bars
Abushanab, Abdulrahman Hamdi; Alnahhal, Wael I ( Qatar University Press , 2021 , Poster)The state of Qatar bears harsh environment and coastal conditions which stand for most of the year. As a result, steel-reinforced concrete structures are subjected to rapid corrosion and deterioration. Therefore, there is ... -
Performance of Mild Steel and Corrosion-Resistant Steel Rebars in Chloride-Contaminated Concrete
Sohail, Muazzam Ghous; Al Nuaimi, Nasser; Alnahhal, Wael; Kahraman, Ramazan ( Qatar University Press , 2023 , Conference Paper)Reinforced concrete (RC) infrastructure in Arabian Peninsula is subjected to harsh climatic conditions of high temperatures, humidity, and airborne chlorides and there is a high concentration of salts in seawater and soils. ... -
The Effect of Surface Treatment of Basalt FRP Bars on the Shear Capacity of Oneway High-Strength Concrete Slabs
Al-Hamrani, Abathar; Alnahhal, Wael ( Qatar University Press , 2023 , Conference Paper)Corrosion is a common condition encountered by steel reinforcing bars which has a considerable negative impact on the structural integrity of concrete structures. Nowadays, applying anti-corrosive composite materials such ...
