ABSTRACT
Presently, construction industries worldwide are looking for materials with low carbon footprint and environment friendliness, yet ordinary Portland cement (OPC)–based materials are widely used in building sectors and remain responsible for the majority of carbon pollution. The deterioration that happens in such concretes from the very beginning of the service life not only reduces their lifespan, but also demands more OPC. Furthermore, continuation and repairs are mostly labor-intensive and too expensive. Thus, self-recovery of the damaged concretes is significant concerning environmental mitigation and energy savings. Lately, nanomaterials-based concretes have been exploited diversely in construction and engineering owing to their enhanced mechanical and durability attributes. The design, as well as production, of self-healing and sustainable concrete is an intensely researched topic in nanotechnology. In this view, this chapter provides a comprehensive assessment on nanomaterials-based self-healing concretes. The past development, recent trends, environmental impacts, sustainability, and merits and demerits of several methods of self-healing concrete production are discussed.
