The construction sector is facing increasing pressure to reduce embodied carbon, resource consumption and construction waste while maintaining the structural performance, durability and economic viability of infrastructure. This research investigates sustainable and low-carbon construction materials as alternatives to conventional cementitious and aggregate-based materials, with particular emphasis on supplementary cementitious materials, recycled aggregates and waste-derived construction materials. The study proposes an integrated Performance–Durability–Carbon–Life-Cycle Cost (PDCLC) assessment framework for evaluating sustainable material alternatives for future infrastructure. The proposed methodology combines material characterisation, mechanical performance assessment, durability evaluation, embodied carbon analysis and life-cycle cost assessment. Key engineering indicators, including compressive strength, tensile and flexural performance, water absorption, durability behaviour, embodied CO₂ emissions and whole-life cost, are evaluated to establish the relationship between material composition, engineering performance and sustainability outcomes. A multi-criteria assessment approach is then proposed to identify material solutions that provide an appropriate balance between structural performance, durability, carbon reduction and economic feasibility. The research aims to address an important limitation in existing sustainable-material studies, where environmental performance, engineering performance and economic implications are frequently assessed independently. By integrating these dimensions within a single decision-support framework, the study provides a systematic approach for selecting low-carbon materials according to infrastructure requirements and life-cycle performance. The proposed framework can support the development of resource-efficient buildings, roads, bridges, precast systems and modular infrastructure while promoting construction-waste utilization and circular material practices. The research contributes to the advancement of sustainable civil engineering by providing a practical performance–carbon–cost-based methodology for low-carbon material selection. The outcomes are intended to support engineers, construction professionals, project managers and infrastructure decision-makers in reducing environmental impacts while maintaining technical and economic performance. The study therefore contributes to the wider development of resilient, resource-efficient and low-carbon infrastructure and establishes a coherent research direction at the intersection of civil engineering, sustainable construction, material innovation and construction cost management.
