Effect of Nano Silica on the Compressive Strength of Concrete ijtsrd
Concrete is one of the most important materials in the construction world. In the present scenario, due to the various industrialization, especially in the urban areas, the demand of construction work increases progressively. Due to which there is very high demand of concrete. So, it is very important to improve the durability and properties of concrete. For this there are various admixtures which are partially replaced with the cement like fly ash, slag, silica fumes, rice husk etc. However, in the present situation, Nano technology comes as a very faithful approach for improving the strength and durability of the concrete. In this project, M30 concrete is used and we use Nano silica of size 236nm as a partial replacement in concrete. Nano silica enters into the pores of the concrete and sets early due to which the permeability and strength of concrete are improved. An experimental analysis has been done by replacing the cement with Nano silica by increasing its percentage as 0.5 , 1 , 2 and 3 b.w.c. The results show that with increase in amount of Nano silica, the compressive strength increases up to 3 , however, if amount of Nano silica goes beyond 3 , the compressive strength of concrete starts decreasing. In these experimental tests, there are 10 cubes prepared with the sample and tested at 7 and 28 days.
