Fly Ash Based Geopolymer Concrete Open Access Journals

Fly ash is a byproduct of coal obtained from thermal power plant. It is also rich in silica and alumina. In this paper, fly ash is used to produce a geopolymer concrete. Geopolymer is a material resulting from the reaction of a source material that is rich in silica and alumina with alkaline solution.

Fly Ash-Based Geopolymer Concrete: Australian Journal of ...

Geopolymer concrete is a ‘new’ material that does not need the presence of Portland cement as a binder. Instead, activating the source materials such as fly ash that are rich in Silicon (Si) and Aluminium (Al) using high alkaline liquids produces the binder required to manufacture the concrete. Hence, concrete with no cement. This paper ...

Fly Ash-based Geopolymer Lightweight Concrete Using ...

In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium silicate and NaOH), and foam was added to the geopolymeric mixture to produce lightweight concrete. The NaOH solution was prepared by dilute NaOH pellets with distilled water.
