OPTIMUM PROPORTION OF BAGASSE ASH -GEOPOLYMER COMPOSITION AS A PARTIAL REPLACEMENT OF FINE AGGREGATE

Abstract

Research carried out in past suggest improvement in compressive strength by replacement of bagasse ash and geopolymer.
From the sugar factoy by-product in the form of bagasse ash as available in the form of pozzolonic material tactically at throw
away prices. If not dealt with properly it increases pollution and related health hazards and may disturbed the ecological
balance. If it can be used to replace the cement not only above issues can be tackled but it will also help to reduce the cost of
concrete. So as to find optimum bagasse ash content as a replacement of cement. Various percentage like 5%,10%,15%,20%
by weightt of cement were used for the choosen grade of concrete M20,M25,M30.Cube are casted and tested to find strength
at the age of 3,7,28 days of concrete using normal curing procedure that is ponding. The variation of various grades of
concrete are shown in figures shown below. The fig-:1indicates that 5% bagasse ash use to replace cement gets the maximum
compressive strength at 3 days of curing after that as the bagasse ash percent increases the strength reduces very fast.
