Abstract
The development of construction materials technology, particularly concrete is growing very rapidly in the presence of nanotechnology. One of the material that deserves the attention of researchers is nanosilica. Use of Nano silica is gaining importance due to its vital characteristics, which helps in developing concrete. In this the influence of nanosilica on durability of concrete has been investigated. For this purpose 2.5% of nanosilica have been added to concrete mixture by replacing some amount of cement. Also the admixture plaster of paris is used to increase workability. In this M25 grade of concrete is used. Durability has been investigated through Water absorption, Sorptivity and Acid attack test. Results of this study showed that nanosilica can be effective in improving the durability of concrete.
