Concrete, steel, glass, and timbers are the most common materials, being used in the field of modern construction.
If we compare these properties with those of a carbon nanotube, the results are astonishing. A carbon nanotube has a Young’s modulus of 1054 GPa, a tensile strength of 150 GPa and a density of 1.4 g-m-3. Thus a carbon nanotube has strength of 150 times that of steel and at the same time approximately six times more
lighter.
Based on the above statistics, it was thought (in UK Delphi Survey 1990), that the Construction industry would benefit the most from Nanotechnology. However, Construction industry lags behind other industrial sectors in terms of appealing investment from large corporate sectors.
Nano-technology is a technology that enables to develop materials with improved or totally new properties. It is an extension of the sciences and technologies already developed for many years to examine the nature of our world at an ever smaller scale. A nanometer is one billionth of a meter. Nano particles is defined as a particle that has at least one dimension less than 100nm. The size of the particle is very important because at the length scale of the nanometer, i.e. 10-9m, the properties of the material actually become affected.
