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 ...
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 ...

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 ...
Carbon nanotube effect on the ductility, flexural strength, and permeability of concrete
(
Hindawi Limited
, 2019 , Article)
Recently, remarkable types of carbon nanofilaments called carbon nanotubes (CNTs) have raised the interest of many concrete and cementitious composite researchers due to their significant mechanical, electrical, thermal, ...
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 ...
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 ...
