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 ...
Steel Reinforced Grout for Strengthening of RC T-section Beams Deficient in Shear
(
Qatar Univesrity Press
, 2020 , Conference Paper)
numerous causes. Thus, proper strengthening and rehabilitation techniques are required
to restore the strength and extend the service life of the structures. Steel reinforced
grout (SRG) has recently been introduced as an ...
Investigation of the Effect of the Force-Frequency on the Behaviour of a New Viscous Damper for Railway Applications
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The primary purpose of this work is to experimentally investigate the damping
coefficient of a viscous damper, intended to be used in railway applications to reduce
noise emission. The viscous shock absorber used in this ...
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) ...
Concrete Hydration Model Characterization Using Evolutionary Optimization
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Pile thermal integrity assessment by means of temperature measurement has received
increasing attention in recent years. The thermal integrity testing method measures
temperature changes during the concrete curing process; ...
The Investigation of an Efficient and Effective Proactive Pipeline Integrity System
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this paper, we propose the investigation of an efficient and effective proactive pipeline
integrity system that uses multi-sensors for monitoring and inspection of the pipeline.
Although the focus is on the pipeline, ...
Use of 3D Images to Evaluate Formation Damage Induced by Montmorillonite Fines in Porous Media Systems
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Formation damage costs oil and gas industry $140 billion/year in lost productivity, this
is a key challenge to Qatar, the world's largest LNG exporter. During production from
a well, multiphase flow foster drag forces to ...
Effects of Using Seawater and Recycled Coarse Aggregates on Plain Concrete Characteristics
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Using seawater and/or recycled coarse aggregates (RCA) for concrete mixing is deemed
advantageous from a sustainability perspective. This paper reports on the results of an
experimental study on fresh and hardened properties ...
Dynamic Imaging of Hydrate Specific Area Evolution during Xenon Hydrate Formation
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Gas hydrates are ice-like structures formed under high pressure and low temperature
conditions. They are considered as a potential energy source due to their abundance
and the increase in energy demand worldwide. A fundamental ...

(
Qatar Univesrity Press
, 2020 , Conference Paper)
Sustainable buildings and related construction techniques are becoming increasingly
recognized within the urban planning development in Qatar. The study aims to develop
an analytical review of sustainable green projects ...
