The construction industry is responsible for a significant portion of global carbon dioxide emissions,
primarily due to the production of ordinary Portland cement and the high energy demand associated with
conventional concrete manufacturing. In response to global climate objectives and sustainable development
policies, there is an urgent need to develop low-carbon alternative binder systems and environmentally
responsible concrete technologies.
This doctoral research aims to investigate and develop sustainable concrete materials with substantially
reduced carbon footprint while maintaining mechanical performance, durability, and structural reliability.
The study will focus on the partial replacement of clinker with supplementary cementitious materials, the
optimization of binder compositions, and the evaluation of microstructural development and long-term
performance.
The research will combine experimental investigation and performance assessment. Laboratory work will
include characterization of raw materials, evaluation of hydration behavior, analysis of phase development,
and microstructural examination. Mechanical properties such as compressive and flexural strength will be
assessed alongside durability-related performance indicators, including resistance to chloride ingress,
carbonation, sulfate attack, shrinkage, and freeze-thaw cycles.
A key objective of the project is to establish relationships between binder composition, hydration
mechanisms, pore structure refinement, and macroscopic performance. By understanding these interactions,
the research seeks to define optimised mix designs that achieve reduced carbon emissions without
compromising structural safety.
The study may further explore innovative processing techniques, mixture optimization strategies, and
potential applications in modern construction systems. As the research progresses, specific objectives and
methodologies may be refined based on experimental findings and emerging scientific developments.
The expected outcome of this doctoral work is the generation of new knowledge regarding the design and
performance of low-carbon sustainable concrete materials, supporting the advancement of environmentally
conscious construction practices.
