EFFECT OF NANO SILICA ON CONCRETE MIX DESIGN IN RIGID PAVEMENT

Abstract

India is the second greatest highway framework on the earth. Owing of rising oil costs and an all the more firmly money related condition, cement is transforming into an all the more appealing decision compared to other road. Ministry of Road Transport and Highways in India saw that advance society can work effectively on concrete roads. The principle concentration now daily is toward the including of Nano silica sand in concrete for enhancing quality of concrete mix design to cope up ever increasing higher load carrying capacity vehicles on pavement. In my examination, at first M40 grade of concrete is outlined. In the mix, Nano silica sand has been taken into consideration by replacing Nano silica sand in measurements of 1%, 2%, 3%, 4% & 5% by the weight of cement to
study the logical properties according to code by testing for workability, compressive and flexure strength. The rigid pavement thickness design utilizing IRC 58:2011 with various extent of Nano silica sand to find out cost effective rigid pavement design. The result shows that solid blend with Nano silica sand ends up being productive and can be suggested for pavement decision makers and contractors.
