Nanotechnology Applications in Steel

Of course, steel is a major construction material that can exist in multiple forms such as bars, I-beams, channels, etc. Nanotech can be used to develop nanostructured steel to increase strength.

It is possible to develop new, low carbon, high performance steel, with very good properties such as higher corrosion-resistance and weldability through the addition of nano copper.

Nanotechnology Applications in Coating

Surface treatment of concrete is an economical and effective method to improve the quality of surface layer and protect the concrete structure. Coating is a type of surface treatments that adds an external layer of coating on the concrete surface that can protect concrete to external detrimental substances.

Nanomaterials (such as nanoclay) have been recently implemented into the polymers that make up the coating to develop what is called as “nanocomposites”. Nanocomposites showed significant improvement in the performance of coating compared to same coatings made without nanomaterials.


To monitor and/or manage the environment’s state and the performance of the materials and structures, nano sensors have been invented and brought to use in the construction industry.

One advantage of these sensors is their significantly small dimensions (10 -9m to 10-5m).

These sensors might be incorporated into the structure while it is being built.

A low-cost, multi-functional piezoceramic device called Smart Aggregate has been used to monitor early age concrete parameters like moisture, temperature, relative humidity, and early age strength development.

The sensors can also be applied to monitor steel corrosion and concrete cracking.

Monitoring the health of a structure may also be done using the smart aggregate.

Nano sensors can monitor internal stresses and cracks during the service life of structures.

They have the ability to give an early warning of the structure’s health before a failure of the structure may happen.
