摘要：The article presents the state of the art and the most important tendencies of one of the most promising sectors within the scenario of technological innovation in constructions: the application to materials and components of the nanotechnologies, a kind of technologies that modify at infinitesimal scale the physical, chemical and mechanical characteristics of materials in a way which is not with the traditional technologies. A sector that has seen in the last years an exponential increase of technical solutions and brevets, most of them being born in other industrial sectors and then transferred and suited for the construction industry, to improve the performances of the materials used in terms of maintenance and conservation, performances, energy saving, aesthetics.
