The Effect of Surface Treatment of Basalt FRP Bars on the Shear Capacity of Oneway High-Strength Concrete Slabs
( 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 ... -
The effect of track load correlation on ground-borne vibration from railways
( Academic Press , 2017 , Article)In predictions of ground-borne vibration from railways, it is generally assumed that the unevenness profile of the wheel and rail is fully correlated between the two rails and the two wheels of an axle. This leads to ... -
The impact of electric field on the demulsification efficiency in an electro-coalescence process
( Elsevier , 2023 , Article)In this study, the influence of the electric field and its determining parameters such as voltage, inter-electrode distance and frequency on the demulsification efficiency of a water-in-oil emulsion was studied. The numerical ... -
