A REVIEW ON NANO TECHNOLOGY IN CONCRETE

Now-a -days Nanotechnology is the advanced technology in Science and Research. In the field of Civil Engineering nano materials offers higher results than the micro materials. The particle size in nano materials ranges from 1nm to 100nm because of this vary the specific surface areas of various materials ranges like 200.1m2 /kg and 321.6m2 /kg. The applications of nano technology in Civil Engineering are many. The reduction of shrinkage and swelling in self compacting concrete are done through nano technology. The compressive strength were multiplied by the use of nano tubes and nano clay(nano metakaolin).Nano sensors are utilized in construction part to understand early age properties of concrete. The subsequent are the review papers that give the use of nano technology in Civil Engineering constructions.
