Regulatory Frameworks for the Successful Implementation of Construction and Demolition Waste Treatment Infrastructure
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In an ever expanding world, our constant need to construct and to support a constantly
growing population is resulting in significant increase in construction waste. Rapid
expansion is a trend that can be seen throughout ...
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 ...
The Use of Measuring While Drilling and Wireline Logging to Identify the Geological Strata in Qatar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In the field of engineering and construction in the Middle East, it is a common practice to
economize a geotechnical investigation using a conventional scope, based on the lowest
price. This tends to compromise the project ...

(
Qatar Univesrity Press
, 2020 , Conference Paper)
The case of a box pushing tunneling method in rock, on Doha Metro Gold Line project,
successfully implemented to connect multiple entrance structures of Sport City station
under a live traffic junction, in a heavy urban ...
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 ...
Influence of Aspect Ratio on the Bearing Capacity and Correlated Modulus of Subgrade Reaction for Shallow Foundations on Dense Sand
(
Qatar Univesrity Press
, 2020 , Conference Paper)
One of the most fundamental problems in the field of geotechnical engineering is the
prediction of bearing capacity and settlement of shallow foundations on cohesion-less
soil subjected to vertical central loading. The ...
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 ...
Resource Recovery from Waste, Water and Wastewaters with Membrane Technologies
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this study, critical elements (Boron (B) and Rare Earth Elements (REE)) recovery is
studied with membrane technologies. Concentrated boron can be recovered by using
different technologies. Membrane technologies such as ...
Structural Efficiency of Steel Stiffening Deck Systems in Suspension Bridges Due to Gravity Loads
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this paper, suspended stiffened decks in suspension bridges are considered. Three
steel deck-stiffening systems are compared structurally; the plate girder, the box girder
and the stiffening truss. A three-span continuous ...
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) ...
