Pore networks to characterize formation damage due to fines at varied confinement and sand shape
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Carbon sequestration in geological formations is in demand for many applications, especially energy production from hydrates. During gas production in a sandy hydrate reservoir, two phase flow and changes in confinement ...
Grouping minimum REV of porosity and tortuosity based on descriptors of sand grains
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
In sandy reservoirs, selecting a representative elementary volume (REV) for the pore scale, is essential for predictive upscaling toward the reservoir scale. The porosity and tortuosity of a sand media are used for REV ...
Status quo and critical review of PPV safe limits for subsurface construction blasting close to low-rise buildings
(
Taylor and Francis - Balkema
, 2013 , Conference Paper)
Subsurface construction blasting may result sever man-made ground vibrations.Waves generated due to detonating a charge in a solid medium like rock generate particle movement and travel at different wave velocities. As ...
A framework for construction workspace management: A serious game engine approach
(
2012 ASCE International Conference on Computing in Civil Engineering
, 2012 , Conference Paper)
Construction workspace is regarded as one of the main constraints on construction sites. Construction workspaces are generally difficult to proactively plan and manage due to the dynamic nature of a site where workspace ...
Nanoscale evaluation of multi-walled carbon nanotube’s performance on resisting oxidization of asphalt
(
Trans Tech Publications Ltd
, 2019 , Conference Paper)
Nanotechnology has contributed significantly to different subfields of the construction industry, including asphalt pavement engineering. The improved properties and new functionalities of the nanomaterials have provided ...
Study on the use of low field nuclear magnetic resonance for detecting asphalt aging
(
CRC Press/Balkema
, 2017 , Conference Paper)
Authors of this paper recently introduced the application of Low Field Nuclear Magnetic Resonance (LF-NMR) to evaluate the aging state of asphalt mix samples. This method was able to determine the aging trends of asphalt ...
Fatigue characterisation of full-scale pavements using viscoelastic continuum damage approach for qatar
(
CRC Press/Balkema
, 2015 , Conference Paper)
The population and economy in Qatar have been expanding significantly in the past six years. Accordingly, Qatar is encountering huge development in infrastructure. The existing mix design methods have been developed in the ...
Characterisation of fatigue resistance of alternative pavement design for the state of Qatar
(
Taylor and Francis - Balkema
, 2014 , Conference Paper)
Asphalt mixtures have been designed in the past in the State of Qatar to safeguard against permanent deformation associated with high temperatures. These mixtures are typically designed to have low content of unmodified ...
Assessment of linear and nonlinear viscoelastic responses of warm-mix asphalt binders
(
CRC Press/Balkema
, 2015 , Conference Paper)
Warm-Mix Asphalt (WMA) technology is widely used in the paving industry due to its impact on reduction of asphalt mixing and compaction temperatures. Characterisation of WMA in the past had focused on evaluating the linear ...
Characterisation of air voids in w-fam samples using x-ray ct imaging
(
CRC Press/Balkema
, 2018 , Conference Paper)
This study documents the use of high-resolution X-Ray Computed Tomography to characterise air void distribution in Fine Aggregate Mixtures (FAM) prepared using Warm Mix Asphalt (WMA) additives (W-FAM). Specimens were imaged ...
