Abstract: Nanotechnology is one of the most active research areas that relate to the number of disciplines including Civil engineering and it may have a great impact on the field of construction materials. The literature survey shows that little is reported to evaluate the durability aspect of HSC ( High strength concrete) incorporating Colloidal nano silica (CNS). This paper deals with studying the effect of CNS on durability properties of HSC subjected to acid attack (H2So4, and HCL) by conducting the tests such as Compressive strength, Weight loss, SCM, ESD and linear regression analysis etc. The experimental study is carried out on M 60 grade of concrete with varying percentage of the P-63 grade of fly ash from 5% to 25 % and P-100 grade of fly ash with constant 10 % replacement by weight of cement (b.w.c) also the percentage of CNS varies from 1% to 5% b.w.c The result shows that 20% replacement of cement by fly ash and 3% addition of CNS gives satisfactory results when compared with other mix proportions.
