Abstract

This paper presents a discussion of factors affecting the performance of fly ash based geopolymer, and some recent innovations on fly ash based geopolymer. The characteristics of fly ash based geopolymer are discussed in terms of the effects of raw material selection, alkaline activators, and curing procedures. Nowadays, researchers have used geopolymer as a cementitious material to develop innovative geopolymer materials, such as porous, fibre reinforced and foam fly ash based geopolymer concrete, which are greener than the traditional cementitious material. The high-calcium fly ashes could be used to produce porous fly ash based geopolymer composites with satisfactory mechanical properties. The addition of fibres increases greatly the ductility of geopolymer. Foam can be added to the geopolymeric mixture to produce lightweight concrete. However, the manufacturing of fly ash-based geopolymer foam concrete has not been explored too much.
