Nanotechnology can be used for design and construction processes in many areas since nanotechnology generated products have many unique characteristics. These characteristics can, again, significantly fix current construction problems, and may change the requirement and organization of construction process. To enhance properties of material used in construction. To satisfy the general aspect of people wanting more quality, control & reliability. To reduce cost of constructing structures.

Concrete is one of the most common and widely used construction materials. Nanotechnology is widely used in studying its properties like hydration reaction, alkali silicate reaction (ASR) and fly ash reactivity. With the addition of nano-SiO2 part of the cement is replaced but the density and strength of the fly-ash concrete improves particularly in the early stages. Fiber wrapping of concrete is quite common today for increasing the strength of pre-existing concrete structural elements.
