The Effect of Different Parameters on the Development of ...This paper presents the experimental results of an ongoing research project on geopolymer lightweight concrete using two locally available waste materials—low calcium fly ash (FA) and oil palm shell (OPS)—as the binder and lightweight coarse aggregate, respectively. OPS was pretreated with three different alkaline solutions of sodium hydroxide (NaOH), potassium hydroxide, and sodium ...
"Chloride Effect in Fly Ash Geopolymer Cement" by Evan DimmickAug 25, 2021 · The production of ordinary portland cement (OPC) poses a significant impact on the world's carbon dioxide emissions through the wide global use of concrete. Geopolymer cements (GPC) made from alkali activated fly ash can serve as a replacement to OPCs, reducing the carbon dioxide emissions by as much as 80%. GPCs exhibit adequate or superior mechanical performance to OPCs.
Geopolymer Concrete REPORT | Concrete | Fly AshGEOPOLYMER CONCRETE REPORT: ABSTRACT Cement is the world's most adaptable, strong and solid development material. By water, cement is the most utilized material, which required expansive amounts of Portland cement. Conventional Portland cement generation is the second just to the vehicles as the significant generator of carbon di oxide, which dirtied the air.
