Abstract

Abstract. Cement being a major contributor to carbon emission needs a revolution in its production or modification to the existing cement. One such way to reduce cement usage is to replace the cementitious compound with a suitable material that does not alter the original purpose of cement in concrete. The sugarcane bagasse ashes (SCBA), which are ashes from biomass burning, are found to act as supplementary cementitious material. Moreover, studies were conducted to relate the strength and durability of concrete by the percentage of replacement of sugarcane bagasse ash to cement. The studies revealed that the SCBA imparts more strength to cement at 10% replacement when compared to 20% replacement. However, this study is intended to use 20% of SCBA replacement in cement by adding silica fume. Concrete being mainly reinforced with steel has the problem of corrosion. To overcome the problem of corrosion as well as to reduce the use of cement and to attain the compressive strength of 10% replacement of SCBA. This experiment is intended to analyze the behavior of concrete up to 20% replacement of SCBA with silica fume at different concentrations such as 0%,5%,10%,15%.

Summary

Introduction

Utilization of industrial and agricultural waste as source of raw material for the construction of encourages sustainable and pollution free environment and provides the economic situation. One of such fibrous waste product from the sugarcane refining industry is sugarcane bagasse ash. The usage of 15 % of SCBA for replacement of cement does not affect the compressive & tensile strength of concrete [1] Result is such that by replacing 15 % of bagasse ash, high strength concrete can be produced. Adding 15% silica fume increases compressive strength & split tensile strength [3].Adding silica fume in 10% - 20% of cement increases ITZ (interfacial transition zone) around aggregate [4].in this paper we are going to use bagasse ash as a replacement of cement with 20% by altering the amount of silica fume such as 0% ,5% ,10% and 15%
