Throughout the developing world, many small and medium scale industries choose to produce energy by burning inexpensive, abundant agricultural wastes instead of more costly conventional energy sources such as coal, oil, and gas. Seasonal cycles of crop production yield high variability in boiler feedstock, with the bulk of the resultant ash subsequently dumped in local landfills. In Muzaffarangar, a small industrial city in northern India, this can mean hundreds of tons of ash landfill being produced daily. The objective of this work has been to perform physicochemical characterization of the ash in order to utilize it as the primary ingredient in sustainable masonry products, thereby creating value where there was originally only waste. Chemical activation of the boiler ash has been the focus of this investigation, with specific interest aimed at understanding the formation and presence of sodium and calcium aluminosilicate networks in the resulting brick samples.
