In this study, the values of the pozzolanic activity, tensile splitting strength, water absorption, porosity, unit volume weight and the specific weight of the concrete mixed with ground waste glass powder have been determined. The ground waste glass powder which was used in the experiments was added by being replaced with the cement in the percentage of 0%, 5%, 10%, 15%, 20% into the concrete. In the preparation of the samples; the aggregate, which was 16 mm (dmax) of maximum grain diameter was used. The samples of cube in the sizes of 100x100x100 for the experiments of the tensile splitting strength, water absorption, porosity, unit volume and specific weight were prepared. The samples were steeped in standard water cure during 7, 28, 90 days in 20?2°C.The tests were applied to the samples of which the cure process was completed. It was observed that the pozzolanic activity of the additive of glass powder occurred. The tensile splitting strength of the concrete in future years showed an increase according to the control concrete. It was observed that the optimum usage value of glass powder was 15% and 20%.
