Abstract. This paper reviews the state of the field of nanotechnology in concrete. Definitions of nanotechnology, including nanoscience and nano-engineering in concrete, are provided. The impact of recent advances in instrumentation and computational materials science and their use in concrete research is discussed.

Loading time is important due to the behavior of the tested material that can be time-dependent (e.g. plastics, concrete, wood, etc. exhibit creep) but also due to the e?ect of thermal drift. Thermal drift is a characteristic of the temperature sensitive electronics and the whole apparatus and is typically in the range 0.1 ? 1nm/s.
