The critical element for sustainable growth in the construction industry is the development of alternative cements. A new technological process called geopolymerization provides an innovative solution, and the presence of aluminum and silicon oxides in fly ash has encouraged its use as a source material. Use of Geopolymer can reduce CO2 emission from the manufacture of concrete since geopolymer binders are produced using industrial by-products, such as fly ash and blast furnace slag instead of Portland cement. This study provides new insight into the strength development and the effect of the molarity and particle size of the fine aggregate in the geopolymer mortars. The results are mainly influenced by the amount of precursors and alkaline activators. While increase of the quantity of additives in GGBS based geopolymer mixtures enhances compressive strength. Hence the proportion of additives to GGBS plays the major role in achievement of acceptable strength with curing condition. Suitable mixtures were found for ambient curing conditions that contained GGBS and lower proportions of RHA.

Alkali-activation, ground granulated blast furnace slag, silica fume, compressive strength.
