In this study, the compressive strength and nanoindentation were analyzed by incorporating different types of waste glass beads (spherical (B) and crushed (CB)) as moisture carriers for internal curing to improve the mechanical properties of high-strengthstes Nanoindentation results showed an increase in density in both ITZ and paste regions. Therefore, it is believed that the potential of WGB has been demonstrated and can cement composites.
