nanotechnology for smart civil engineering
- 1. BY:MD NEHAD NAZIM B.TECH 1ST YEAR CIVIL ENGINEERING INTEGRAL UNIVERSITY LUCKNOW
- 2. Nanotechnology is the skill and science of manipulating matter at the Nanoscale. The word “Nano” which emanates from the greek word for dwarf, designates a billionth. Nanotechnology is not a new science or technology, it is rather a boost of the sciences and technologies which already subsist from many years and it is logical progression of the work that has been done to analyze the nature of our world at an even minute scale.
- 3. The construction business will inevitably be a beneficiary of this Nanotechnology. It can be used for design and construction process in many areas since, nanotechnology generated products have many unique characteristics. Many disciplines of civil engineering, in convergence with design and construction process can be profited from this technology. For example, new structural materials with unique properties stronger and lighter composites, self-disinfecting surfaces, air cleaners, Nano sized sensors etc. Literally Nanotechnology in civil engineering is to enhance properties of material used in construction and to satisfy the general aspects of people i.e., of quality, control and reliability.
- 4. Following are some listed of Nanoparticle and their role in smart construction field: 1.Slurry of amorphous Nano-(Sio2)- Improves segregation resistance in self compacting concrete(SCC). 2.Nano-silica (SiO2)- displace part of the cement to densify the concrete and gain. 3. Oxidiesd multi-walled Nanotube(MWNT)- Increase compressive strength and flexural strength in concrete. 4.Micro encapsulated healing polymer(Smart Material)- Automatically closes the cracks in concrete when they occur. 5. Fumed silica Nanoparticles – Fire protective glass. 6. Organically modified bentonite asphalt- Road construction with more durability.
- 5. Concrete is one of the most familiar and broadly used construction material. It is a mixture of Portland cement and aggregates and water or rocks. The key to achieving a strong, durable concrete rest in the careful proportionating and mixing of the ingredients. Typically, a commix is about 10 to 15 percent cement, 60 to 75 percent aggregate and 15 to 20 percent water. Entrained air in many concrete commixes may additionally take up another 5 to 8 percent.
- 7. Topmix permeable concrete is that innovative techniques for permeable pavement with a base and sub-base that allow the movement of storm-water through the surface. Topmix permeable accommodates 36,000 millimeter of water an hour, or approximately 1056 gallons every minute. This topmix permeable paving is effective in managing runoff from paved surfaces, on the railway tracks for smooth running of trains in rainy season and on the roadways and highways for better transportation. Tarmac, a UK building materials and solutions company generated topmix permeable to divert rainwater during storms.
- 9. Sustainable construction is defined as all who produce, develop, plan, design, build, alter, or maintain the infrastructural environment. The construction industry follows the following vision for sustainable development: 1. To regenerate of housing, particularly to rejuvenate town centre socially and economically. 2. Planning communities to reduce car use. 3. Minimising mineral extraction. 4. Protection of the countryside. 5. Utilization of energy and water more efficiently. 6. Genuinely industries plays an integral character in providing a better quality of life through its workout.
- 10. It reveals the utmost need of application of nanotechnology in the field of construction for sustainable development. Research in this field could pay heroic dividends in the areas of technological breakthroughs and economic boon. In shorts, this paper wrap up with a strategic plan on how civil engineering can be profited with the implementation of nanotechnology resulting in construction of smart structures.
