Sustainable Low Carbon Concrete for Future Infrastructure

Confirmation seminar presented by Hashen Kalansooriyage

The global construction industry currently encounters substantial challenges, notably the scarcity of conventional construction materials and the increasing issue of waste generation. Integrating recycled waste materials into concrete applications has emerged as a promising strategy to mitigate these dual challenges, balancing economic feasibility with environmental sustainability. This study rigorously evaluates the viability of using recycled aggregates and supplementary cementitious materials as replacements for traditional aggregate and cement in concrete pavement applications. The evaluation will involve a thorough material characterization and an assessment of the mechanical and durability performance of the waste-based concrete. Based on these assessments, recommendations will be provided for structural road infrastructure design principles and specifications.
