Mechanical Properties of Concrete with Partial Replacement of Bagasse Ash

Abstract

— The utilization of industrial and agricultural waste produced by industrial processes has been the focus of
waste reduction research for economical, environmental, and technical reasons. Sugar-cane bagasse is a fibrous wasteproduct of the sugar refining industry, along with ethanol vapor. This waste product (Sugar-cane Bagasse ash) is
already causing serious environmental pollution, which calls for urgent ways of handling the waste. Bagasse ash mainly
contains aluminum ion and silica. In this paper, Bagasse ash has been chemically and physically characterized, and
partially replaced in the ratio of 0%, 5%, 15% and 25% by weight of cement in concrete. Fresh concrete tests like
compaction factor test and slump cone test were undertaken was well as hardened concrete tests like compressive
strength, split tensile strength, flexural strength and modulus of elasticity at the age of seven and 28 days was obtained.
The result shows that the strength of concrete increased as percentage of bagasse ash replacement increased.
