Fly Ash-Based Geopolymer Concrete

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. Geopolymer concrete is

Corrosion Evaluation of Geopolymer Concrete Made with Fly

Jan 04,  · and bottom ash as a replacement of fine aggregates for developing geopolymer concrete. However, corrosion evaluation of geopolymer concrete made with both fly ash and bottom ash precursor material has been rarely reported. The focus of this paper is to develop a sustainable fly-ash based geopolymer concrete with a 50% replacement of bottom ash.
