A Review Paper – on the Use of Nanotechnology in Construction Industry

This paper reviews the state of field of nanotechnology in concrete technology field. The outstanding chemical any physical property of nanomaterials helps in structural reinforcement and redemption of environmental pollution, and also in producing self cleaning materials. Concrete is one of the most used materials in structural applications, where strength, costing, durability of playing a key role in high attribute of concrete. In this paper we tried to review the application of nanotechnology in concrete production. The paper first presents general information and definitions of nanotechnology. Then, it focuses on the most effective nano- additives that can increase the rheological and hardened properties of concrete
