Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Concrete is the most commonly used materials for construction in Qatar as well as in
the world. Exposure to sever environmental conditions causes physical deterioration
of concrete structures and significantly affect ...
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 ...
An Artificial Intelligence Approach to Estimate Travel Time along Public Transportation Bus Lines
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Public transportation sectors have played significant roles in accommodating passengers
and commodities efficiently and effectively. The modes of public transportation
often follow pre-defined operation schedules and routes. ...
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 ...
Mechanical and durability properties of ultra-high performance steel FRC made with discarded materials
(
Elsevier
, 2021 , Article)
This study investigates the mechanical and durability properties of 12 ultra-high performance fiber reinforced concrete (UHPFRC) mixes manufactured using alternate aggregate sources. Natural gabbro aggregates (GA), steel ...
Performance Evaluation of Vehicle Restraint Systems in the Context of Design and Installation
(2021 , Article)
Vehicle Restraint Systems (VRS), a necessary component of the road design, are widely implemented by transport authorities to protect vehicles from severe incidents, mainly colliding to the roadside as well as median ...
Near Surface Embedded Application for FRCM Strengthening of RC Beams in Flexure
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this paper, the efficacy of a recent strengthening technique, referred to as Near Surface
Embedded (NSE), has been investigated for flexural strengthening of Reinforced Concrete
(RC) beams using Fabric Reinforced ...
Parametric study on moment redistribution of fiber reinforced concrete continuous beams with basalt FRP bars
(
Qatar University Press
, 2020 , Poster)
The state of Qatar is suffering from its 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. ...
Utilizing Steel Slag in the Removal of Suspended Solids from Dewatered Construction Water
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Construction dewatering is an operation used to remove shallow groundwater that
infiltrates construction sites. After recovering this water from the construction sites, the
water is either discharged to the sea, injected ...
Optimum Dispersion Parameters of Carbon Nanotubes: Concrete Strength by Response Surface Methodologies
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"This paper implements Response Surface Methodologies (RSM) techniques to illustrate
the maximum carbon nanotubes (CNTs)-concrete mechanical properties responses to the
length, weight fraction and treatment variables. ...
