WebOct 1, 2016 · A few mix design methodologies have been proposed earlier for GPC. Of them all, Lloyd and Rangan (2010) were the first to propose a mix design methodology for fly ash based geopolymer concrete. According to this method, density of GPC has been assumed as 2400 kg/m 3 and the total aggregates content was fixed at 80%. WebTypical concrete consists of sand/gravel bound together by Portland cement. In the concretes studied in this project, the sand/gravel will be replaced with recycled glass, and all of the Portland cement will be replaced with fly ash, which is a fine ash produced when coal is burned to generate electricity.
WebIt was found that the fresh fly ash based geopolymer concrete was viscous, cohesive and dark in color. After making the homogeneous mix, workability of fresh geopolymer concrete was measured by flow table … WebApr 19, 2024 · For mix design purposes, fly ash itself should be considered like portland cement, except that the specific gravity for fly ash is different. The specific gravity of portland cement is typically 3.15, while the specific gravity of fly ash may range from 2.2 to 2.8, depending on fly ash composition.
