In this study, the characteristics of density and flow value of mortar substituted heavy weight waste glass were compared with the aggregate ratio. From the results, the density and flow value increase as the substitution of waste glass increase, however, it is considered that the increase of the aggregate ratio of 30% or more does not contribute to the increase of the density.
