Abstract: The US National Science Foundation (NSF) supports fundamental research in all fields, including materials for construction and rehabilitation of infrastructure, which is specifically supported by NSF’s Civil and Mechanical Systems (CMS) Division. NSF has been the lead government agency in the National Nanotechnology Initiative. Many scientific discoveries have resulted, especially in electronic and biomedical fields. Recently, attention has been drawn to the opportunities that nanotechnology may offer in more traditional fields, including infrastructure and infrastructure materials. Potential results of research in the area include strong, fast-curing and ductile concrete, self-healing structures, self-cleaning surfaces, switchable coatings, high strength reinforcements, and new sensing and actuating materials and devices. In response, CMS research funding is now moving to increase support for research on nanomaterials for construction. A number of NSF-supported projects are under way, including application of nano particles for coatings, use of nanoscience tools for understanding material behavior such as hydration of Portland cement, infiltration of nano size materials in existing structures to extend their life, nano devices for monitoring infrastructure and use of nano electronics for safety and energy consumption. Some examples of active projects are presented in this paper, which also provides an outline of future vision and challenges.
