Abstract
The cement industry is a significant source of carbon dioxide (CO₂) emissions, representing a considerable portion of global emissions. To address the urgent need to reduce the environmental footprint of the construction sector, nanotechnology has been increasingly explored as a viable solution. This study presents the production process of nanocement, which involves the direct growth of carbon nanotubes (CNTs) on cement grains. When used as a partial substitute for traditional cement (10%) in mortar, nanocement significantly enhances mechanical properties while also promoting sustainability by reducing CO₂ emissions by 20%.
