Increasing Compressive Strength Property Of Bagasse Ash Blended Concrete By Using Chemical Activator (naso4)

The use of sugar cane bagasse ash is being studied for application in the constructionrnindustry because of its technical, economic and to a large extent, environmentalrnadvantages. This study has investigated the improvement of early strength development ofrnconcrete containing bagasse ash by addition of chemical activator. rnbagasse replacement is done 10%, 20% and 30% by volume of cement and casted withrnand without activator. rnThe compressive strength properties of bagasse ash blended cement paste, mortar andrnconcrete with and without activator were studied. The results indicate that bagasse ashrnblended concrete gives higher strength when activated with sodium sulfate. rnX- ray diffraction test also held on bagasse ash blended cement paste casted and cured forrn7days and 28 days. The result verified the strength improvement is due to increasing thernbagasse pozzolanic activity.
