Nanotechnology and its impact on construction: Bridging the gap between researchers and industry professionals

Nanotechnology research and product development are actively conducted in many industries, (such as industries that manufacture advanced materials and semiconductors) and in medicine. Few studies have presented the potential application areas of nanotechnology in, and the needs of, the construction industry while identifying the benefits and barriers of entry in research and development. Some construction industry sectors follow research and development in nanotechnology; however, the industry does not take on a leadership role. With proper knowledge of the potential products and techniques offered through an investment in nanotechnology, the construction industry may potentially improve the efficiency of its processes and offer better products to clients such as those that exist in building and infrastructure construction and in environmental and petroleum engineering. This paper analyzes the understanding of nanotechnology in the context of construction and explores the current status of nanotechnology in the construction industry. Findings from a literature review, from a survey among construction industry professionals, and from expert interviews with leading researchers in construction-related nanotechnology research and development are presented to identify the potential benefits and existing barriers of using nanotechnology in construction. A multi-criteria decision analysis (MCDA) framework was developed to rank application areas of nanotechnology that will have major effects in the construction industry. Tasks were identified that will make the application of nanotechnology in construction successful in the future.
