EVALUATION OF SUSTAINABLE GREEN CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT BY BANANA LEAF POWDER AND CATTLE BONE POWDER

Abstract :

Aim of this thesis is to reduce the CO2 emission by reducing the cement consumption in construction industry there by creating an environmental friendly sustainable green concrete for modern construction world. Supplementary Cementitious Material (SCM) can partially replace cement in concrete and thereby reduces the consumption cement. Already material like fly ash, groundnut shell ash, rice husk ash, leaf ash, periwinkle shell ash are used as SCM’s to reduce the cement content with increase in strength parameters. But, when SCM’s are used in ash form, loss of energy and emission of CO2 creates negative impact. An alternate method of using waste materials as SCM in powder form increases the strength parameters of concrete. Combination of waste Banana Leaf Powder (BLP) and Cattle Bone Powder (CBP), when used as SCM increases the strength of concrete. Banana leaf Powder serves as an alternate binding material where as Cattle Bone Powder, rich in calcium content improves the binding property of cementitious substances with aggregates thereby improves the bond strength between cement phase and aggregate phase. Compressive strength test on hardened concrete of M20 grade of concrete is conducted and the strength increase by about 20–30% at 28 days. Also cracking in BLP and CBP used concrete is lesser than that of the control specimen.
