Progress of sugarcane bagasse ash applications in production of Eco-Friendly concrete - Review

Abstract

Cement is a non-replaceable, versatile component of concrete which is highly used in world in all construction works. Demand for cement has been increasing day by day where emission of CO2, over-use of natural resources like lime stone, shale has become environmental problems. To balance this, supplementary cementitious materials are encouraged which involves less use of cement in concrete. Agricultural wastes like bagasse ash, rice husk ash, palm oil ash have been tested for their performance in concrete with partial replacements of cement. Countries like Brazil, India are largest producers of sugarcane, faces scarcity of land due to dumping of raw bagasse. Processing of sugarcane bagasse collected from factory scrap by cleaning and incinerating alters the morphological characters of sugarcane bagasse ash making it fit for using as pozzolanic admixture. It is proved that desired workability, gain in strength, reduction in permeability, resistance to thermal and electrical conductivity are observed in sugarcane bagasse ash replaced concrete when compared with conventional concrete.
