There is research in Brazil about the development of carbon nanotubes to cement.

Carbon nanotubes are like steel cables added to the material.

The carbon nanotube cement (or carbon nanotube concrete) can generate a concrete proton in the order of 200MPa (Mega Pascal)

In Brazil the research indicates the use of the carbon nanotube concrete for the infrastructure works of the underwater constructions, due to its low porosity.

According to Professor Carlos Alberto Achete, coordinator of the Inmetro's Metrology Materials Division (National Institute of Metrology, Standardization and Industrial Quality, which today is considered a center of excellence in the field of nanotechnology based on carbon). sectors most benefited by nanotechnology will be civil construction. "It will be heavily affected as it will add intelligent materials such as graphene, nanotubes, organic light-emitting devices, nanofluids and tribological coatings, among others, enabling the development of end products with better performance, longer durability and lower weight."

I believe that these solutions could be considered, Brazil accepts partnerships in this area.
