Effect of Nanotechnology on Physical Properties of Concrete

Abstract:

The focus of this paper is the study of effect of nanotechnology on the concrete. It shows that:The control of moisture in buildings is key to their durability, functionality, health and efficiency. Concrete which is thoroughly soaked with water is less rigid in compression than concrete with is thoroughly dried out. Use of nano SiO₂ could significantly increase the compressive for concrete, containing large volume fly ash, at early age and improve size distribution. The self-healing polymer could be especially applicable to fix the microcraking in bridge, piers and columns. With the hycrete waterproofing system, concrete is batched with hycrete liquid admixture to achieve hydrophobic performance. Concrete treated by hycrete shows less than 1% absorption. This product has positive effects on the environment. Green additive has lower cost than the materials they replace. Finally, two solutions are given to have appropriate material behavior: nanotechnology and green additive.
