Sustainable utilization of waste carbon black in alkali-activated mortar production
(
Elsevier
, 2021 , Article)
This article investigates the potential utilization of waste carbon black (WCB) resulting from the aluminum industry as a by-product material in the fly ash-based geopolymer composites production. Experimental study was ...
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 ...
Evaluation of Bond Strength Between Carbon Fiber Reinforced Polymer (CFRP) Composites with Modified Epoxy Resins and Concrete
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Rehabilitation and strengthening of concrete structures are becoming more significant
in civil engineering applications. The use of externally bonded Fiber Reinforced
Polymers (FRP) is one of the methods to strengthen and ...
Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Concrete is the most commonly used materials for construction in Qatar as well as in
the world. Exposure to sever environmental conditions causes physical deterioration
of concrete structures and significantly affect ...
Thermal behavior and post-heating fracture characteristics of polypropylene microfiber-reinforced geopolymer binders
(
Elsevier
, 2022 , Article)
This paper investigated the post-heating behavior of fly ash-based geopolymer binders reinforced with polypropylene (PP) microfibers. Geopolymer binders with different fiber contents including 0%, 0.05%, 0.1%, and 0.2% by ...
