Life Cycle Assessment (LCA) of Recycled Concrete Incorporating Recycled Aggregate and Nanomaterials

AbstractNanotechnology is widely used in construction to advance high performance and durability materials, as represented by concrete, in which nanomaterials such as nanosilica (SiO2), nano-alumina (Al2O3), and nanotitanium oxide (TiO2) are used to replace cement as a partial binder. Suitable amounts of adding these nanomaterials are beneficial with regard to the mechanical, economic, and environmental aspects of concrete.
