Preparation and Characterization of Geopolymer Cement [PDF]
Journal of Scientific Research in Science, 2016 Effect of some artificial pozzolana such as ground granulate blast furnace slag (GGBFS), cement kiln by-pass dust (CKD), silica fume (SF), and fly ash (FA) on geopolymer composition and its resistance to sulphate attack was studied. Various mixes are prepared using different liquid/solid ratios (L/S) by weight.
