Summary
Decarbonizing the construction industry is critical to achieving global net-zero emission targets by 2050, as the sector is one of main contributors of global CO₂ emissions, particularly due to cement production and the extensive use of non-renewable raw materials. The availability of bio-based materials presents an opportunity to develop more sustainable construction products. Incorporating bio-based materials into cement and concrete systems not only reduces carbon emissions and energy demand but also supports resource efficiency and circular economy strategies. Therefore, advancing bio-based materials for construction industry is essential for a sustainable built environment.
This special issue aims to highlight recent advances in the valorization of bio-based materials in cement and concrete applications. Bio-based materials, including but not limited to, husks, fibers, biochar, and waste from agricultural and related industries, fall within the scope.
Contributions that demonstrate the integration of bio-based materials into cement and concrete applications are welcomed. Manuscripts addressing, but not limited to, the following themes are encouraged:
· Innovative utilization of bio-based materials, including recycling and upcycling
· Treatment and activation methods of bio-based materials
· Design and manufacturing processes of bio-based materials
· Environmental impact and safety assessment
