Fly ash is the fine solid particulate residue driven out of the boiler with the flue gases in coal-
fired power plants. Now it can be used for making geopolymer which acts as a cement-like …

In recent years, attempts to increase the utilization of fly ash as a replacement for ordinary
Portland cement (OPC) in concrete have increased in significance. Geopolymer concrete …

Geopolymer is an environment-friendly binder, which has gained significant interest
amongst the research community in last few decades. Previous studies show that low …

This research was conducted to compare geopolymers made from fly ash and ground
bottom ash. Sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solutions were used …

Fly ash based geopolymer is a green cementitious material with the potential to replace
portland cement. Due to the changes of raw coal and coal combustion technology in recent …

To reduce greenhouse gas emissions, efforts are needed to develop environmentally
friendly construction materials. This paper presents the development of fly ash-based …

Owing to the high viscosity of sodium silicate solution, fly ash geopolymer has the problems
of low workability and rapid setting time. Therefore, the effect of chemical admixtures on the …

Nano-SiO2 is a non-toxic, tasteless, and pollution-free material with hydroxyl groups that
facilitate the adsorption of water on its surface. Nano-SiO2 is characterized by small particle …

In this study, fly ash was added to residual soil to produce soil–fly ash geopolymer bricks.
This study investigated the effects of fly ash/soil, alkali activator/ash, Na 2 Si O 3/KOH (or …

This research investigates the effect of the physicochemical characteristics of five cognate fly
ashes on the mechanical properties of Class F fly ash-based geopolymers synthesized with …
