Material performance and cost effectiveness of seawater-mixed rubberized concrete
(
Elsevier
, 2021 , Article)
The combined use of seawater and recycled tire aggregate (RTA) in concrete is potentially a way forward towards sustainable construction. It can help control harvesting of natural aggregates, manage waste tires, mitigate ...
Comparing models of problem and project-based learning (PBL) courses and student engagement in civil engineering in Qatar
(
Modestum LTD
, 2020 , Article)
Background: While improved student engagement has been highlighted as an essential goal and a major outcome of Problem and Project-Based learning (PBL), little empirical evidence has been provided regarding types and forms ...
Impact of high turbidity on reverse osmosis: Evaluation of pretreatment processes
(
Desalination Publications
, 2020 , Article)
This study evaluates the performance of sand filtration (SF) and ultra-filtration (UF) as pretreat-ment processes for reverse osmosis (RO) for seawater with turbidities of 4.8, 23.2, and 99.7 NTU. For seawater with a ...
A hybrid nf-fo-ro process for the supply of irrigation water from treated wastewater: Simulation study
(
MDPI AG
, 2021 , Article)
Municipal treated wastewater could be considered as a water source for food crop irrigation purposes. Enhancing the quality of treated wastewater to meet irrigation standards has become a necessary practice. Nanofiltration ...
Comparison of nanofiltration with reverse osmosis in reclaiming tertiary treated municipal wastewater for irrigation purposes
(
MDPI AG
, 2021 , Article)
This study compares the performance of nanofiltration (NF) and reverse osmosis (RO) for the reclamation of ultrafiltered municipal wastewater for irrigation of food crops. RO and NF technologies were evaluated at different ...
Investigating nonlinear forced vibration behavior of multi-phase nanocomposite annular sector plates using Jacobi elliptic functions
(
Techno-Press
, 2020 , Article)
A multi-scale epoxy/CNT/fiberglass annular sector plate is studied in this paper in the view of determining nonlinear forced vibration characteristics. A 3D Mori-Tanaka model is employed for evaluating multi-scale material ...
Nonlinear forced vibrations of multi-scale epoxy/CNT/fiberglass truncated conical shells and annular plates via 3D Mori-Tanaka scheme
(
Techno-Press
, 2020 , Article)
In the context of classic conical shell formulation, nonlinear forced vibration analysis of truncated conical shells and annular plates made of multi-scale epoxy/CNT/fiberglass composites has been presented. The composite ...
Assessment of transient vibrations of graphene oxide reinforced plates under pulse loads using finite strip method
(
Techno Press
, 2020 , Article)
Based on a refined shear deformation finite strip, transient vibrations of graphene oxide powder (GOP) reinforced plates due to external pulse loads have been investigated. The plate has uniformly and linearly distributed ...
Electrochemical behavior of mild and corrosion resistant concrete reinforcing steels
(
Elsevier
, 2020 , Article)
An experimental study is carried out in this paper to evaluate the corrosion performance of mild steel reinforcing bars (MS), high strength steel reinforcing bars (HS), epoxy-coated steel reinforcing bars (EC), and ...
Durability characteristics of high and ultra-high performance concretes
(
Elsevier
, 2021 , Article)
Durability characteristics of high-performance concrete (HPC) and ultra-high performance concrete (UHPC) are evaluated in comparison to normal strength concrete (NSC). HPC and UHPC are cast using commonly available materials ...
