Abstract

Increasing construction cost and environmental sustainability are persistent issues of concern in the built environment. Consequently, new generation materials are required for practical applications in order to considerably tackle the challenges. This work focused on the fabrication and testing of precast concrete slab panels produced using industrial by-products - foundry sand, as a partial replacement of fine aggregate, and ground granulated blast furnace slag as cement admixture. Foundry sand was substituted for manufactured sand in levels 0%, 10%, 20%, 30%, 40% and 50%, while granulated blast furnace slag (GGBS) was constantly added to cement at 30%, in a standard designed M40 concrete grade. The result showed that 40% of foundry sand was adequate for appreciable strength development in the modified mix. The same mixture was also found to have better insulation characteristics than the conventional mix. The wall panels tested in this study are quite economical when compared to competing building technologies.
