Behavior of Concrete with the Addition of Nano Silica, Fly Ash, and Waste Foundry Sand

Rabikanta Chanam and Balwinder Lallotra

Abstract

This paper examines the behavior of nano silica (NS) as well as fly ash (FA) as a fractional alternative of cement and waste foundry sand (WFS) as a fractional substitute of fine aggregate in concrete. The amount of FA is kept constant as 10% of cement. The optimum amount of WFS is determined as 20% by checking at 10%, 15%, 20%, and 25% as a fractional substitute of fine aggregate. The proportions of FA (10%) and WFS (20%) are not varied for all the different mixes and the number of NS is varied as 1%, 2%, 3%, and 4%. The different concrete properties are determined using different laboratory tests and are compared to a normal control mix (M 30). The mix with 2% NS, FA 10% and WFS 20% is found out to be the optimum mix. Scanning electron microscopy (SEM) test is used for studying microstructure. After the test outcomes it is deduced that the use of NS, FA, and WFS does not only help in waste disposal reduction but also in producing quality concrete.
