Nanotechnology for Concrete Multifunctionality and Decarbonization Concrete infrastructures are at risk of premature failure due to degradation, which can compromise their serviceability and reliability. Substantial efforts are required to maintain aging infrastructures in a safe and serviceable condition. Recent advances in intelligent or multifunctional concrete, combined with nanotechnology, show promise in addressing these issues and potentially enhancing functionalities such as self-healing and self-monitoring, thereby adding value to smart infrastructure. Compared to conventional concrete, properly designed intelligent concrete can optimize the strength, serviceability, durability, and other functions of infrastructures. It can also reduce life-cycle costs, resource consumption, and environmental impacts. Decarbonization through nanotechnology offers a promising pathway forward, including the utilization of solid waste and carbon capture technologies in construction material prod
