This research discusses use of industrial byproducts in masonry construction materials using alkali-activation. This work will describe material and process considerations towards production of a high compressive strength brick using residual material such as biomass derived boiler ash. This material has many undesirable characteristics for alkali-activation compared with the traditional coal fly ash, including varying shape, large particle sizes ranging from 5-600 μm, loss on ignition between 8-35%, and less than 4% alumina. When combined with supplementary materials in the form of clay and lime, high compressive strengths are observed in the bricks made with these materials, demonstrating the robustness of the proposed mix design. Furthermore, early strength development is observed, as more than 55% of the 28 day strength is achieved after one day curing. Economic and environmental analysis shows that this product has reduced environmental impact, making them a viable alternative to traditional materials in the market.
