Abstract

Nanotechnology is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. Traditionally, nanotechnology has been concerned with developments in the fields of microelectronics, medicine and materials sciences. However, the potential for application of many of the developments in the nanotechnology field in the area of construction engineering is growing. The properties like self-sensing, self- rehabilitation, self-structural health monitoring, self-vibration damping, self-cleaning and self-healing are studied. Nanotechnology deals with understanding, controlling and manipulating matter at the level of individual atoms and molecules in the range of 0.1–100 nm (10-9 m). It creates materials, devices, and systems with new properties and functions. In civil engineering and construction, the nanotechnology is applied in (i) concrete for reducing segregation in self-compacted concrete; (ii) the use of nano sensors in construction phase to know the early age properties of concrete is very useful. The present paper reviews the state of the art on the use of nanotechnology in the field of civil engineering and construction and also discusses its future prospect. Following this the study were carried out in ductile structural composites along with its enhanced properties, low maintenance coatings, better properties of cementious materials, reduction of the thermal transfer rate of fire retardant and insulation, various nano sensors, smart materials, intelligent structure technology etc. Finally the future trend, potential and implications of nanotechnology development in civil engineering towards more economical infrastructure, low cost maintenance with longer durability are deliberated.
