Abstract

Exfoliated vermiculite is inventive equivalent to fine aggregate generating towards unique light weight concrete with rise in characteristics of concrete when converged with traditional concrete, in this research analysis M30 grade contrasting form of concrete samples have been composed. Exfoliated Vermiculite is adapted as replacement to fine aggregate along with various admixtures of mineral being Fly ash, dolomite, silica fume, ground granulated blast furnace slag, and Metakaolin as a fractional replacement for cement. Research has been done on the concrete's mechanical aspects. According to this study, replacing five to ten percent of fine aggregate with vermiculite improved the strength of all admixtures. All of the properties have enhance when 10% silica fume is used to replace cement; 10% Metakolin and 40% GGBS has shown greater compressive strength, and 30% dolomite has not shown any effect. The target strength was reached by replacing 20% of the cement with fly ash and 10% of the fine aggregate with vermiculite.
