Hey Dear, look at this article, maybe it will help you.

Conference Paper Nanoscience to nanotechnology for civil engineering: proof of concepts

Hi Salam, I think it is too early to tell.

Structural engineering is an established science with proven principles.

Nanotechnology is an emerging science with interesting properties, but still too expensive to be employed in large scale structural engineering.

Nano technology can be employed to enhace the various properties of cements hence improving cost and other aspects also.

Thank you gentlemen for your great answer

Please share me the best answer might you get...
