Special Issue Information

Dear Colleagues,

The construction industry faces environmental challenges due to resource scarcity and the excessive generation of waste. However, utilizing waste materials in construction offers promising solutions. This Special Issue explores the innovative repurposing of waste materials and their integration into construction processes, exploring the opportunities and challenges associated with leveraging waste for sustainable practices.

The scope of this Special Issue includes, but is not limited to, the following topics:

  • Material Characterization and Performance: Exploring the performance and properties of waste materials in construction, and comparing their mechanical, thermal, and durability properties to traditional materials.
  • Material Composition Optimization: Using AI algorithms to enhance the composition of construction materials by incorporating waste components.
  • Environmental Impact Assessment: Conducting life cycle assessments (LCAs) to evaluate the environmental impact of using waste materials in construction.
  • Durability and Long-Term Performance: Assessing the long-term durability and performance of construction materials containing waste components.
  • Structural Integrity and Load-Bearing Capacity: Evaluating the structural integrity and load-bearing capacity of elements incorporating waste materials.
  • Case Studies and Best Practices: Highlighting successful examples of waste reuse in construction projects.

This Special Issue on waste in construction materials aims to enhance knowledge, promote innovation, and encourage sustainable practices in the industry by examining various research axes.

This study investigates the early hydration characteristics and kinetics of ordinary Portland cement (OPC) and calcium sulfoaluminate cement (CSA) composite pastes. The hydration mechanisms of OPC-CSA systems with different proportions are analyzed through zonal analysis and the Krstulović–Dabić method. The experimental results show that in OPC-dominated systems, an appropriate amount of CSA promotes the rapid hydration of ye’elimite and optimizes the cumulative hydration heat and pore structure. However, excessive CSA inhibits hydration due to alkalinity imbalance. In CSA-dominated systems, 10% OPC increases the alkalinity, promoting ye’elimite to hydrate into ettringite. Higher OPC content hinders the hydration process due to ion concentration imbalance. The kinetics model indicates that CSA accelerates the interfacial reaction and diffusion in the OPC system, while OPC reduces the overall hydration rate of the CSA system. Microscopic analysis confirms that the composite system improves the pore structure through mineral interaction. In the OPC-dominated area, the pore structure is mainly composed of small and dense pores. In the CSA-dominated area, the characteristics of large pores are affected by the expansion properties of CSA and hydration heat. This study constructs a coupling mechanism of alkalinity regulation and crystal nucleus generation, providing a theoretical basis for the design of high-performance composite cement materials.
