Review on Use of Nanotechnology in Civil Engineering

Nanotechnology and Nanomaterials is one of the most active research areas with both science and engineering. The term nanotechnology offers very much elaborate meaning and vast scope that may be changed from field to field. Nanotechnology has many folds and applications in almost all engineering fields. The beginning of nanotechnology has revolutionized the growth of the civil engineering. Building materials domain can be one of the main beneficiaries of these researches, with applications that will improve the characteristics of concrete, steel, glass, bricks and insulating materials. The use of nanomaterials in the composition of some materials, such as cement, will result in significant reductions of CO2 pollution and the use of performance thermal insulations will result in efficient use of energy for air conditioning. The use of nanotechnology controls the topic at the minute level, the properties of matter are sincerely affected. Strength, durability and other properties of materials are dramatically affected under a scale of nanometer (10-9m). Due to the small particle size, nanotechnology focuses on Nanomaterials with unique functions in term of strength, durability, high speed of construction, and environmental impact reduction. This paper presents application of nanotechnology in building materials for various civil engineering works.
