Abstract: Concrete is one of the most widely used construction materials, generating substantial waste during demolition and construction activities. The improper disposal of concrete waste contributes to environmental pollution and resource depletion. Traditional recycling methods have limitations, such as high energy requirements and reduced quality of recycled products. In recent years, nanotechnology has emerged as a promising solution for the treatment and reuse of concrete waste. This paper explores how nanomaterials like nano-silica, carbon nanotubes (CNTs), and nano-TiO₂ enhance recycling efficiency and improve the performance of recycled concrete aggregates (RCA). It also discusses challenges, future prospects, and how nanotechnology aligns with sustainable development goals.
Keywords: Nanomaterials, concrete structures, nano-silica, nano-TiO₂
