The large global production of fly ash and rapid advances in geopolymer technology and knowledge mean that a viable alternative to ordinary portland cement concrete is now available, in the form of alkaline-activated class F fly ash geopolymer concrete. The aim of this research is to examine a potential mix design process for this emerging product. A process that can be worked through in a calculated way in order to find the full range of mix proportions to meet a particular targeted product has not been investigated or submitted to date. This research seeks to bridge this gap, which is currently preventing the more widespread use of geopolymer concrete (GPC). This work is a largely experimental investigation into mixture proportion and strength relationships, attempting to detail a large amount of data which will be utilised at the core of the process to be investigated. The purpose of this experimental investigation is to study the flexural behaviour of fly-ash based geo-polymer ferro-cement elements. Ferro-cement composite is a rich Geo-polymer mortar mix of 1:1. The effectiveness of the Square woven, Square welded and Expanded metal mesh were compared with different layers such as single layer, double layer and triple layer. Results showed that slabs with square welded mesh triple layer were most suitable and cracked at highest load.
