Effect of using Cement Kiln Dust as a nano-material on the strength of cement mortars
(
Springer Verlag
, 2017 , Article)
In this experimental study, the effects of using nano-sized Cement Kiln Dust (CKD) as a partial replacement for Ordinary Portland Cement (OPC) on the strength of cement mortars is investigated. The CKD was milled up to 4 ...
Characteristics of olive mill solid residue and its application in remediation of Pb2+, Cu2+ and Ni2+ from aqueous solution: Mechanistic study
(
Elsevier
, 2014 , Article)
This study investigated the use of untreated olive mill solid residues (OMSR) as a solid extractant for Pb2+, Cu2+ and Ni2+ ions from aqueous solution. It was shown that the solution initial pH value affected the metal ...
Numerical modeling of shear strengthened reinforced concrete beams using different systems
(
American Society of Civil Engineers
, 2014 , Article)
This research aims at creating finite-element models for fiber-reinforced polymer (FRP) shear strengthened concrete beams. It is inspired by the fact that the determination of the structural behavior of shear strengthened ...
Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
(
Korean Society of Industrial Engineering Chemistry
, 2014 , Article)
The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data ...
Evidential Reasoning–Based Condition Assessment Model for Offshore Gas Pipelines
(
American Society of Civil Engineers (ASCE)
, 2016 , Article)
Condition assessment of oil and gas pipelines is a significant component in pipeline operations and maintenance. Such assessments are used to ensure better decisions for repair and/or replacement to reduce pipelines’ failure ...
Estimating the elastic settlement of vertically loaded single piles in rock
(
Trans Tech Publications
, 2014 , Article)
An extensive finite element analysis was performed to study the settlement behavior of vertically loaded piles entirely embedded in non-homogeneous rock. To avoid utilizing interrelated parameters, pile-rock relative ...
Evaluation of Combined Excavation Waste and Reclaimed Asphalt Pavement Aggregates for Use in Road Bases and Sub-bases
(
OMICS International
, 2014 , Article)
More than 15 million tons of aggregates are imported each year to Qatar from neighbouring countries. Large quantities of waste materials (around 20 million tons/year) from excavation waste, demolition rubble and reclaimed ...
Acoustic absorption analysis and modeling of asphalt mixtures
(
ASTM International
, 2019 , Article)
Highway traffic noise is a major environmental issue all over the world. This is particularly annoying to residents who live nearby major transportation corridors. Noise pollution adversely affects the quality of their ...
Evaluation of short-term aging protocol for asphalt mixtures
(
MDPI AG
, 2019 , Article)
Asphalt mixtures are subjected to short-term aging during the production, placement, and compaction processes. Proper evaluation of asphalt pavement performance relies on the accurate characterization of asphalt mixtures ...
A chronological exploration of the evolution of housing typologies in Gulf cities
(
Springer
, 2016 , Article)
This paper traces the evolution of housing typologies in four major cities in the Gulf region, namely Doha, Dubai, Abu Dhabi and Manama. The study reviews the formation and historical events in the region, which had a ...
