Abstract: Nowadays, the Environmental pollution is one of the greatest problems the world is facing which is causing grave & the damage which is not reparable to the world & about 40% humans have died due to air, water & soil pollution. India is now 4th country in the world to generate nearly 2,454,938 kilo tones is carbon dioxide per year. To reduce the carbon emission we can use a material which is called carbon nanotubes (cnt’s ). Carbon nanotubes are the materials which have special properties & great potential in various Civil engineering structure. We can convert the waste gases coming from the industrial & automobile or vehicular exhaust or furnace into nano particles called carbon nanotubes which is almost three thousand times stronger than steel & one sixth of its weight. Carbon nanotubes are currently receiving more interest because is it’s extremely good mechanical properties & are now know to be materials of 21st century. In the present study the effect of addition of carbon nanotubes on properties of concrete to be studied. And the comparison between carbon nanotubes & conventional concrete will carry out.

Keywords:Carbon Nanotubes (CNT’s), Carbon Dioxide, Nano-material, Durability and Strength.
