Effect of Pavement Surface Aging on Tire-Pavement Noise: A Case Study in the State of Qatar
( EDP Sciences , 2018 , Conference Paper)The acoustical performance of asphalt pavements changes with time due to combined effects of environmental conditions and various distresses induced by repeated and heavy traffic. This study examined the changes in the ... -
Effect of rail unevenness correlation on the prediction of ground-borne vibration from railways
( DC/ConfOrg , 2015 , Conference Paper)This paper presents the influence of rail unevenness correlation on the predicted track and ground vibration. The study is based on an integrated railway model in the wavenumber-frequency domain with varying complexity ... -
Effect of self-healing calcium nitrate microcapsules on concrete properties
( National Research Council , 2016 , Article)Self-healing concrete with microencapsulated calcium nitrate was investigated. The compressive strength of concrete admixed with microcapsules (as a percentage of the weight of the cement) was tested and compared with that ... -
Effect of surface roughening on concrete/trm bond
( ISEC Press , 2017 , Conference Paper)Textile reinforced mortar (TRM) is applied on the concrete surface with the aim of strengthening reinforced concrete structures. The performance of the strengthened structural system is directly related to the bond between ... -
Effect of the induced dielectrophoretic force on harvesting of marine microalgae (Tetraselmis sp.) in electrocoagulation
( Elsevier , 2020 , Article)In this study, a new electrocoagulation electrode configuration has been investigated in order to induce dielectrophoretic (DEP) force for the enhanced harvesting of marine microalgae (Tetraselmis sp.). Asymmetrical aluminum ... -
Effect of using Cement Kiln Dust as a nano-material on the strength of cement mortars
( Springer Verlag , 2017 , Article)In this experimental study, the effects of using nano-sized Cement Kiln Dust (CKD) as a partial replacement for Ordinary Portland Cement (OPC) on the strength of cement mortars is investigated. The CKD was milled up to 4 ... -
Effect of using multiple fabric plies on the tensile behaviour of carbon textile reinforced mortar
( University of Cantabria - Building Technology R&D Group , 2020 , Conference Paper)Recently, textile reinforced mortar (TRM) has emerged as a viable strengthening material for reinforced concrete (RC) and masonry structures. Understanding the TRM tensile behaviour is important to achieve an accurate ... -
