Nano in construction
Building with nano
Nano is used in construction to improve the properties and functions of commonly used building materials like:
Stronger, lighter materials
To give you an example, conventional concrete is partly made up of silica. But if you use nano-scale particles of silica in the concrete mix, you can make the structure of the concrete more dense. This means it is better at blocking water and as a result is more durable. Use of carbon nanotubes or nano clays can also help make new lighter, stronger materials which last longer and are easier to work with and more able to resist shocks such as earthquakes.
Sensing for damage
Sensors created using nanotechnologies can be embedded into building materials to sense when the material is damaged or stressed, or to monitor temperature changes and their effect on the building.
