Summary
The growth of waste production from the construction sector, industries and agro-based wastes is a major environmental concern in the modern world. At the same time, the construction sector is one of the largest consumers of energy and natural resources. Therefore, these challenges have encouraged engineers and researchers to explore sustainable alternatives that could reduce waste disposal issues and minimize excessive consumption of natural resources. One of the approaches to incorporating waste materials into cement-based composites has received considerable attention due to its engineering and environmental benefits.
This special issue in the ZKG International journal focuses on recent developments in the utilization of waste materials in mortar, paste, concrete, and other cementitious composites. The submissions related to recycled aggregates, industrial by-products, low-carbon materials, construction and demolition waste, agro-based wastes, alternative binders, waste fibers used as partial or full replacements for conventional materials are welcome. The experimental, analytical and data-driven studies focusing on the mechanical properties, durability, creep and shrinkage, microstructural properties, thermal performance, recycling techniques, circular economy approaches, sustainability assessment, and the prediction of material behavior are within the scope of this issue. This issue provides a platform for engineers, researchers, and industry professionals to share scientific advancements and practical findings contributing to the development of durable and sustainable composite materials for future infrastructure development.
The topics or suggested themes may include, but are not limited to:
· Industrial by-products in cementitious composites
· Agro wastes in concrete and mortar
· Recycling and reuse of C&D waste
· Alternative binders and hydration process
· Waste-derived fibers for reinforced cement composites
· Waste materials in special concretes such as lightweight and self-compacting concretes
· Low-carbon construction materials
· Mechanical and durability properties in short and long terms
· Shrinkage, creep and cracking behaviours
· Microstructural evaluation of cement-based composites
· Circular economy approaches in mortar and concrete
· Sustainability and LCA of cementitious materials
· Artificial intelligence and Machine learning approaches for material design
· Cement-based composites and 3D printing
· Self-healing sustainable concrete composites
· Nano-materials and hybrid waste incorporation in concrete
· Field applications of eco-friendly cement-based composites
