Abstract

The unglazed roof tile waste (URTW) potentially replaces fine aggregate concrete to produce new green concrete at 40, 50, and 60%. This research focuses on investigating the mechanical behaviour of URTW as fine aggregate in the concrete mix design. Both fresh and hardened concrete's physical and mechanical properties will be determined. The concrete’s mechanical behaviour contained URTW compared to the control mix in terms of its workability during slump test and its percentage of water absorption and compressive strength in a hardened state. The current experiment result of the compressive strength test for new green concrete is improved at an increasing percentage of URTW replacement. The result of the mechanical behaviour as to its compressive strength, workability, and water absorption of new green concrete shall be parallel with the standard value of BS. Specifically, the compressive strength of new green concrete achieved the targeted mean strength of M25 grade concrete at every percentage of replacing river sand with URTW.
