Supplementary cementitious blend of metakaolin and nanosilica with ferrochrome slag as fine aggregate in concrete

Abstract

The most abundant materials utilized in construction firm is newlineconcrete. Concrete is the second most used material by society next to the newlinewater. The cement and aggregates composition are major ingredients of newlineconcrete. The cement industry expels the antagonist gas CO2 that eradicates newlinethe Earth atmosphere. Globally 4400 million tons of cement is produced in newlinethe financial year of 2021 as per United States Geological Survey (USGS) newlinereport 2022. The viable supplant for cement is challenging part in concrete newlineproduction. The Supplementary Binding Materials (SBM) is ratified alternates newlinefor cement. This thesis explores initially with finding the best substitution for newlinecement using micro and nano pozzolans to improve the structural durability. newlineMoreover, Metakaolin (MK) and Nanosilica (NS) as micro-nano pozzolans newlinereplaced as SBM. newline
