ST1690: Eco-Tile Aggregate: Closing The Loop On Construction Waste In Concrete Production

Muhammad Adam Hakimi Bin Idris UiTM Cawangan Sarawak

Ceramic tile waste from construction activities has increasingly contributed to
environmental pollution due to its non-biodegradable properties and excessive landfill
disposal. In addition, the continuous use of natural aggregates in concrete production has
raised concerns regarding resource depletion and environmental sustainability. Therefore,
this study explores the potential use of recycled ceramic tile waste as a partial replacement
for coarse aggregates in concrete production. Concrete specimens containing 5% and 10%
crushed tile replacement were prepared and cured for 28 days before undergoing
compressive strength testing. The methodology involved crushing and grading ceramic tile
waste to achieve suitable aggregate sizes before incorporation into the concrete mix. The
experimental findings revealed that the concrete with 10% tile replacement achieved a higher
compressive strength of 30.0 MPa, while the 5% replacement recorded 20.4 MPa. The results
indicate that recycled ceramic tile aggregates can enhance concrete performance while
simultaneously reducing construction waste. Overall, Eco-Tile Aggregate demonstrates
strong potential as an environmentally sustainable material for future concrete applications.
