Each team develops a sustainable concrete mix design using selected low-carbon materials and supplementary cementitious components, balancing strength, durability, and environmental performance. Participants follow standard laboratory procedures for batching, mixing, and curing to ensure consistency and comparability of results. Compressive strength testing at seven days is conducted using calibrated equipment under staff supervision. In the design and presentation session, teams explain their material selection, mix design rationale, and sustainability strategies to a panel of academics and industry professionals. Teams are judged and cash prizes are awarded in three categories: Strongest Cube, Lowest Carbon Content, and Best Presentation. This approach integrates design, experimentation, and communication to enhance applied learning in sustainable concrete technology.
