Potency Of Sugarcane Bagasse Ash Partial Substitution Of Cement In Concrete

the availability of sugarcane bagasse ash produced by Arasoe Sugar Factory, it is not used utilized. That sugarcane bagasse ash has size very fine that it can pollute the air. The sugarcane bagasse ash has silicate content, and it has pozzolan properties. The needs of construction material are something that to think about that. It is an alternative to substitute the using of cement in concrete construction. This study is aimed to find the potential of sugarcane bagasse ash in Arasoe Sugar Factory for partial substitution of cement in concrete. The sample made from the variety of sugarcane bagasse ash 0%, 2.5%, 5%, and 7.5% as partial substitution of cement in concrete. The ratio of water and cement is 0.45. The specimen of concrete is taken care in standard condition at the laboratory and compressive strength test when the sample is in 28, 45, and 62 days old. The compressive strength test refers to ASTM C39/C39M-01 (Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens). The development of compressive strength of concrete with many variations of sugarcane bagasse ash 0% 2.5%, 5% is increasing along with the age of concrete, however in contrast with 7.5% of sugarcane bagasse ash the decreasing in 60 days old later. Partial substitute of sugarcane bagasse ash in concrete is possible to do in an amount about 5% of sugarcane bagasse ash.
