Nanotechnologies in Civil Engineering – A Review
One of the most influential technology in this century is Nanotechnology due to its remarkable and successful
results in various manifolds, Civil Engineering is one of them and to be more precise Construction Industry. Since it effect
the material at atomic level so the properties get altered at microscopic level. With the actualization of Nanotechnology, it
procreate materials desiring higher properties such as durability and strength then traditional materials. The main focus of
Nanotechnology in concrete aims at production and mixing of nano-particles in concrete at appropriate proportions, which
helps in gain in compressive as well as flexural strengths at early stage. Pore structure improvements can also be done by
incorporating nanomaterials in concrete. Due to addition of nanomaterials in concrete the proportion of cement content get
reduced without losing its strength characteristics than traditional concrete thus leads to production of eco friendly concrete
referred as Green Concrete. This paper tries to highlight the usage of nanotechnology in civil engineering and various other
materials viz. glass, wood, steel, its applications in concrete as well as its impacts on construction industry.
