Special Issue Information

Dear Colleagues,

Our world is facing critical environmental challenges due to the extensive release of CO2, and the production and use of concrete contribute a significant portion of these carbon emissions. Meanwhile, the annual production of concrete consumes 4–6 billion tonnes of cement and generates 8% of global CO2 emissions, making construction a carbon-intensive industry. Carbon is mainly produced from the combustion of fossil fuels, and these will remain dominant energy sources for the foreseeable future. To mitigate global warming and the associated environmental changes, reducing the CO2 released by construction and building materials has attracted significant interest.

This Special Issue aims to discuss the new advanced accelerated carbonation technologies to reduce the carbon footprint of construction and building materials, which also have good performance. Areas to be covered in this Research Topic may include, but are not limited to:

  • Low-carbon concrete.
  • Carbon curing.
  • Low-carbon cement.
  • Carbonation mineralization materials.
  • Carbonation of recycled wastes (recycled concrete, IBA, steel slag, etc.).
  • Biological carbonation mineralization.
  • Life cycle assessment (LCA).
  • Theory and simulations on carbonation technologies.
  • Other accelerated carbonation technologies.

The construction industry is essential to the development and economy, but is also the largest generator of construction and demolition waste (CDW). While efforts are made to minimize such generation, the construction industry has been developing applications for it in the form of aggregates to replace the commonly used natural aggregates. However, in structural applications, it is necessary to ensure that the properties of concrete produced with CDW, as recycled aggregates (CDW-concrete), guarantee adequate performance and do not put the structure at risk. For this, one of the alternatives is improving the properties of CDW aggregates through carbonation, a process called carbonate curing or accelerated carbonation. In this sense, this paper aims to investigate the carbonation of CDW aggregates, clarifying how this process occurs, the existing carbonation methods, the main properties that affect this process, and their influence on the properties of recycled aggregates and the CDW-concrete. To this end, the SREE (systematic review for engineering and experiments) method was used to search and analyze scientific manuscripts published without a time limit. The results revealed that the most widely used method for carbonate curing is recommended by Chinese standard GB50082, and highlighted the need for further research to investigate the CDW-concrete, focusing on its eco-friendly potential to capture CO2 from the atmosphere.
