Report on <strong>Nanotechnology</strong> <strong>and</strong> <strong>Construction</strong><br />

The logical conclusion of the research being conducted on materials is that, as well as<br />

buildings, the other areas of engineering structures <strong>and</strong> architecture likely to be affected in<br />

the future are roads <strong>and</strong> bridges, <strong>and</strong> this was indicated by the respondents.<br />

The survey also asked what the possible global market impact of the future applications of<br />

nanotechnology in construction might be. Although difficult to predict, estimates ranged to<br />

billions of euros <strong>and</strong> this is to be expected for the same reasons covered in the section above<br />

on current work. One respondent commented that they thought the economic impact would<br />

extend to the entire cementitious <strong>and</strong> polymer industries.<br />

Most respondents (67%) believed that this future work would impact the construction<br />

industry within 5-10 years <strong>and</strong> the timescale fits with the research intensive nature of the<br />

technology. However, 10 years is close enough that the commercial implications for industry<br />

cannot be ignored <strong>and</strong> the construction business should be looking at these changes sooner<br />

rather than later. At the moment, 4 million tn/yr of TiO 2 pigment are produced globally <strong>and</strong><br />

there seems to be no reason for production not to increase to meet the dem<strong>and</strong>s of the ever<br />

widening field of application in construction. In contrast, only 65 tn/yr of carbon nanotubes<br />

are produced currently worldwide <strong>and</strong> only a 60% growth in production is predicted in the<br />

next five years. It is believed that prices will remain too high for widespread use of carbon<br />

nanotubes in construction, despite dropping significantly from their current 20€ to<br />

1000€/gram. Expensive, small scale production of nanotubes as well as clumping, lack of<br />

binding to the bulk material, <strong>and</strong> temperature effects are therefore key barriers to their<br />

application in the industry. Barriers to further applications of nanotechnology to glass are the<br />

lack of non-metallic CVD coating techniques mentioned above as well as a deficiency of<br />

large scale nanoparticle deposition processes which can be integrated with existing ones at<br />

atmospheric pressure.<br />

Resources for Research<br />

Respondents were asked about the level of research both in the industry as a whole <strong>and</strong> in<br />

their own companies <strong>and</strong> the results are discussed below.<br />
