The main focus of this study is to investigate the pozzolanic attribute of the recycled waste glass powder used as cement replacement. A coarser glass powder (<150 µm) was used and the substitution levels employed were 0, 15 and 30% by weight of cement. A mix design similar to that of fly ash was used in the current experimental program in order to enhance the performance of the glass powder (GP) under investigation. In addition to principal tests like workability, density and compressive strength durability tests like drying shrinkage and resistance to chloride ion penetration were performed. Temperature of the mixes was also evaluated to ascertain the effect of GP on heat of hydration. Test results show that 30% is the ideal replacement level which lead to higher strength reporting a strength activity index (SAI) of over 100%, improved resistance to chloride permeability and lower density, drying shrinkage and temperature.
