Factors Influencing the Mechanical Properties of Geopolymer Mortar Made of Fly Ash
(Civil Engineering, 2020 , Master Thesis)
Geopolymerization is a process where silica and alumina rich source materials turns into excellent binding materials by the aid of alkali solutions. Fly ash class F mainly consists of alumina and silica. Compressive strength ...
Fabrication of Fouling Resistant Ti3C2Tx(MXene) Cellulose Acetate Nanocomposite Membrane for Forward Osmosis Application
(Civil Engineering, 2020 , Master Thesis)
Forward Osmosis (FO) is one of the promising technologies that can be used to combat growing water scarcity. However, FO membrane fouling hinders the widespread application of this technology by significantly reducing the ...
Development of Variable Message Sings Strategies for Traffic Management at Work Zones
(Civil Engineering, 2020 , Master Thesis)
Work zones are defined as road sections of which different activities such as road construction or maintenance take place. In most work zones, road alignments are different than the pre-work periods. Therefore, speed limits ...
Examining Preference For Autonomous Vehicle (Av) Among Qatari Residents
(Civil Engineering, 2020 , Master Thesis)
Because of growing body of researches that predict the autonomous vehicles to be the future mode of transport. It is important to investigate the preference of Autonomous vehicles among Qatari citizens for fast developing ...
A Comparative Traffic Noise Study between Signalized Intersections and Roundabouts
(Civil Engineering, 2020 , Master Thesis)
This study presents a comparative traffic noise study done between signals and
roundabouts in Doha, Qatar. Traffic noise and volume data were collected at four
signals (two 2-lane and two 3-lane) and four roundabouts ...
Shear Behavior of Green Concrete Beams Reinforced with Basalt FRP Bars and Stirrups.
(Civil Engineering, 2020 , Master Thesis)
The Reinforced concrete structures when exposed to a harsh environment it will be susceptible to the corrosion of steel reinforcement and shall lead to deterioration process. Consequently, the service lifetime of the ...
Experimental and Theoretical Investigation on Bond Behavior of Tensile Lap Spliced Basalt Fiber Reinforced Polymer Bars in High Strength Concrete Beams
(Civil Engineering, 2020 , Master Thesis)
Basalt fiber reinforced polymer (BFRP) reinforcements are a possible replacement for corroding conventional steel bars. BFRP bars tension lap splices are necessary due to construction stoppages and limitations on rebar ...
Effect of Curing on the Deterioration of RC Structures in the Arabian Gulf
(Civil Engineering, 2020 , Master Thesis)
The deterioration of concrete in the Arabian Gulf is responsible for reduced service life
of reinforced concrete structures. The reasons for degradation are attributed to the harsh
environmental conditions and the ...
An Enhanced Electrocoagulation Process for The Removal Of Fe and Mn from Municipal Wastewater Using Dielectrophoresis (DEP)
(Civil Engineering, 2020 , Master Thesis)
This study evaluates the removal efficiency of Fe and Mn from primary treated
municipal wastewater using new electrodes configuration in electrocoagulation (EC)
process. The used electrodes configuration generates a ...
