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. ...
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 ...
Significance of GOs, GNPs and CNTs' Nanomaterials on the Mechanical Properties of Cement
(
Qatar University Press
, 2023 , Conference Paper)
This study reports the statistical significance of using Graphene Oxides (GOs), Graphene Nanoplatelets (GNPs) and Carbon Nanotubes (CNTs) on the mechanical properties of cement paste. Samples containing several nanoparticles' ...
RSM Analysis for Optimum Content of Graphene Nanoplatelets for 3D-Printed Clay Strength
(
Qatar University Press
, 2023 , Conference Paper)
This study applies Response Surface Methodologies (RSM) methods to maximize 3D-Printed clay mechanical properties. Mixes containing different Graphene Nanoplatelets (GNPs) contents were printed and tested in compression ...
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 ...
Optimum carbon nanotubes' content for improving flexural and compressive strength of cement paste
(
Elsevier Ltd
, 2017 , Article)
This study investigated the effect of multi-walled carbon nanotubes’ (MWCNTs) weight fraction on the setting time and mechanical properties of cementitious composites. Different cement mixes containing CNT-to-cement weight ...
Characterization of tbm muck for construction applications
(

This paper investigates the potential utilization of the Tunnel Boring Machine (TBM) muck generated from Doha's Metro Gold Line in different construction applications. The properties of the raw TBM muck were studied, and ...
Recycling of Local Qatar’s Steel Slag and Gravel Deposits in Road Construction
(
OMICS International
, 2014 , Article)
Every year, the State of Qatar generates about 400,000 tons of steel slag and another 500,000 tons of gravel as a result of steel manufacturing and washing sand, respectively. The two materials (by-products) are not fully ...
3D-Printed Clay Enhanced with Graphene Nanoplatelets for Sustainable and Green Construction
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2023 , Article)
This paper presents a study on the effects of graphene nanoplatelets (GNPs) on the mechanical behavior of 3D-printed burnt clay, the most sustainable and green construction material, under constant printing parameters. ...
Use of local discarded materials in concrete
(
Elsevier
, 2014 , Article)
Steel slag, a by-product of steel manufacturing, is generated in large quantities in Qatar. In fact, it is estimated that more than 400,000tons of steel slag are generated annually in the country. Gravel, resulting from ...
