Life Cycle Assessment for Fiber-Reinforced Polymer (FRP)nComposites Used in Concrete Beams: A State-of-the-Art Review
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Fiber-reinforced polymer (FRP) composites have become popularly utilized in structural
engineering applications. The common use of the FRP composites is related to their
economic benefits that can be observed right away ...
High and Ultra-high Performance Concretes: A Solution to Reinforced Concrete Durability under Harsh Climate of Arabian Gulf
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Reinforced concrete (RC) infrastructure in the Arabian Gulf region deteriorates under
severe environmental conditions after only short service life. To overcome this problem,
it is imperative to employ high-quality concretes ...
Impact of Draw Solution Concentration on Forward Osmosis Process: A Simulation Study
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this study, a simulation model was used to evaluate the performance of forward
osmosis process. A solution of low salinity was used as the feed solution in forward
osmosis to dilute saline solution (i.e. draw solution) ...
Predicted and Back-calculated Coefficients of Permeability of Randomly Fractured Rock Mass: A Case Study
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents the discrepancy between the coefficients of permeability measured
for randomly fractured limestone using field falling-head tests and that back-calculated
for the same rock mass based on the actual ...
Parametric study on moment redistribution of fiber reinforced concrete continuous beams with basalt FRP bars
(
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 ...
Long-Term Cost Performance of Corrosion-Resistant Reinforcements in Structural Concrete
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Corrosion, which leads to the premature deterioration of reinforced concrete (RC)
structures, is increasingly an issue of global concern. Accordingly, corrosion-resistant
materials have emerged as alternative reinforcement ...
Effect of Alkaline Activators on the Mechanical Properties of Geopolymer Mortar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Geopolymerization is a process where silica and alumina rich source materials turn
into excellent binding materials by the aid of alkali solutions. Materials such as fly ash
are by-products in energy power plants. Fly ...
Comparison of the Mechanical Behavior of Railroad Ballast in a Box Test under Sinusoidal and Realistic Train Loadings Using Discrete Element Method
(
Qatar Univesrity Press
, 2020 , Conference Paper)
A ballasted track is a popular type of railway track and its use is increasing all over the
world. A ballasted track consists of different structural elements like rails, fasteners,
sleepers, ballast layer, sub-ballast ...
Release of colloids in saturated porous media under transient hydro-chemical conditions: A pore-scale study
(
Elsevier
, 2021 , Article)
The deposition and consequent release of colloids pose a significant challenge to the environment, groundwater quality and human health. Subsurface soil contains numerous types of colloids that exhibit a diverse range of ...
Effects of soaking process on CH4-CO2 replacement efficiency for hydrate-bearing sediments
(
Elsevier
, 2021 , Article)
CH4-CO2 replacement method has the advantages of sequestering carbon dioxide and sediment stability compared to other methods such as depressurization and thermal stimulation. However, the production efficiency using CH4-CO2 ...
