Life cycle cost analysis of sustainable reinforced concrete buildings with treated wastewater, recycled concrete aggregates, and fly ash
( Elsevier , 2023 , Article)The global excessive demand for concrete has resulted in a significant depletion of concrete natural resources and substantial release of carbon emissions in the environment. To tackle such challenges, treated wastewater ... -
Mechanical characteristics of ultra-high performance steel FRC made with recycled concrete aggregates
( American Institute of Physics Inc. , 2023 , Conference Paper)Recycled concrete aggregates (RCA) are increasingly becoming a sustainable alternative to natural aggregate (NA) for concrete applications. This study, therefore, tests the influence of RCA on the fresh and hardened ... -
The Influence of Reinforcement Ratio on the Shear Behaviour of Sand Coated Basalt FRP Bars Reinforced Beams
( Springer Science and Business Media Deutschland GmbH , 2022 , Conference Paper)Qatar is known by its harsh corrosive environment that is represented by high periodical humidity, and dust accompanied by temperature fluctuation. Also, geographically Qatar is considered a peninsula, this in turn makes ... -
Characteristics of Concrete Made with Treated Domestic Wastewater
( Springer Science and Business Media Deutschland GmbH , 2022 , Conference Paper)The dramatic increase in the worldwide production of concrete and its consequences in depleting freshwater resources has become an urgent challenge among researchers. Many countries use the desalination treatment method ... -
Flexural Capacity of Sustainable RC Beams Manufactured with Treated Wastewater, RCA, and Fly Ash
( Springer Science and Business Media Deutschland GmbH , 2023 , Conference Paper)Sustainable concrete with recycled materials has recently received considerable interest among researchers. Of the available recycled materials, treated wastewater (TWW), recycled concrete aggregates (RCA), and fly ash ... -
Mechanical Characteristics and Durability of Concrete Made with Treated Domestic Wastewater and Recycled Concrete Aggregates
( East Carolina University , 2022 , Conference Paper)Massive amounts of fresh water and natural aggregates are annually used for concrete applications, resulting in a rapid depletion of freshwater and natural aggregate resources. This necessitates the need of replacing fresh ... -
Bond Strength of Basalt FRP Bars with Different Surface Treatments to Plain and Fiber-Reinforced Concrete
( Springer Science and Business Media Deutschland GmbH , 2023 , Conference Paper)The current study presents an investigation on the influence of the surface texture of the reinforcing bar and the addition of macro fibers to concrete on the bond strength of basalt fiber reinforced polymers (BFRP) bars. ... -
Flexural vibration attenuation properties of phononic crystals
( Trans Tech Publications Ltd , 2019 , Conference Paper)Phononic crystals (PCs) have the ability to have phononic bandgaps dependent on the acoustic properties of its constituent materials (i.e., mass, elasticity). Forming a 1D periodic variation using a viscoelastic material ... -
Experimental and numerical investigation of the flexural behavior of one-way RC slabs strengthened with near-surface mounted and externally bonded systems
( Elsevier , 2024 , Article)This study investigated the flexural performance of one-way reinforced concrete (RC) slabs strengthened with two distinct strengthening systems: near-surface mounted (NSM) bars and externally bonded (EB) carbon fiber-reinforced ... -
Flexural Behavior of Basalt Fiber-Reinforced Concrete Slab Strips with BFRP Bars: Experimental Testing and Numerical Simulation
( American Society of Civil Engineers (ASCE) , 2020 , Article)This study investigated the flexural behavior of a new one-way concrete slab system reinforced longitudinally with basalt fiber-reinforced polymer (BFRP) bars and cast with basalt fiber-reinforced concrete (BFRC). The study ... -
Evaluating prestress losses in a prestressed concrete girder railway bridge using distributed and discrete fibre optic sensors
( Elsevier , 2020 , Article)This paper evaluates the data collected during a comprehensive monitoring campaign aimed at capturing the prestress loss behaviour of four 11.9 m prestressed concrete beams. These beams formed part of the superstructure ... -
Simulation of axial tensile well deformation during reservoir compaction in offshore unconsolidated methane hydrate-bearing formation
( Elsevier , 2021 , Article)Sand production encountered in the 2013 offshore field gas production tests at the Nankai Trough, Japan, could be attributed to well failure during reservoir compaction. In this study, well integrity under various reservoir ... -
