Nanotechnology in Civil Engineering Construction Field
Nanotechnology in Concrete: Concrete is a mixture of cement, sand (fine aggregate), coarse aggregate water. As concrete is most usable material in the construction industry it's been required to improve its quality. The mechanical behaviour of concrete materials depends on phenomena that occur on a micro and a nano scale.

Nanotechnology and Concrete | Concepts and Approach
The structure of cement derivatives (cementbased materials) is complex and not fully understood. They are formed by selfassembly of different chemical species in a specific way to form basic building blocks (or units); the size of these units is on the order of a few nanometers. After they are formed, these basic units arrange themselves into larger units, still nanometric in size, which ...
