Predicted and Back-calculated Coefficients of Permeability of Randomly Fractured Rock Mass: A Case Study
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents the discrepancy between the coefficients of permeability measured
for randomly fractured limestone using field falling-head tests and that back-calculated
for the same rock mass based on the actual ...
Long-Term Cost Performance of Corrosion-Resistant Reinforcements in Structural Concrete
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Corrosion, which leads to the premature deterioration of reinforced concrete (RC)
structures, is increasingly an issue of global concern. Accordingly, corrosion-resistant
materials have emerged as alternative reinforcement ...
Effect of Alkaline Activators on the Mechanical Properties of Geopolymer Mortar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Geopolymerization is a process where silica and alumina rich source materials turn
into excellent binding materials by the aid of alkali solutions. Materials such as fly ash
are by-products in energy power plants. Fly ...

COVID-19 is a virus that has infected more than one hundred and fifty million people and caused more than three million deaths by 13th of Mai 2021 and is having a catastrophic effect on the world population's safety. ...
Shear capacity of reinforced concrete deep beams using genetic algorithm
(
IOP Publishing Ltd
, 2020 , Conference Paper)
It is vital to understand the shear behaviour of reinforced concrete (RC) beams in order to avoid a catastrophic shear failure and design for ductile failure. However, due to the complexity in the shear failure mechanism ...
The Factors Affecting CO Emission in the European Union Countries: A Statistical Approach to Sustainability across the Food Industry
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
The research investigates four prime factors influencing CO2 emission levels associated with the food production industry in the European Union (EU) member states. The prime factors, namely population size, percentage of ...
