Development of sustainable geopolymer composites for repair application: Workability and setting time evaluation
( Elsevier , 2023 , Other)One of the most used construction materials worldwide is concrete. It has a lot of advantages over the other construction materials. However, the production process of concrete produces a huge amount of carbon dioxide. ... -
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 ... -
Repair and Rehabilitation of Damaged Reinforced Concrete Beams Using Sustainable Geopolymer Composites
(2024 , Master Thesis)Cement is one of the most used building materials worldwide. However, using cement affects the environment negatively by increasing CO2 emissions during its manufacturing process. In addition to that, concrete structures ... -
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 ... -
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 ... -
