The Effect Of Variations Of Palm Oil Shell Waste And Fly Ash On The Compression Strength Of Concrete

Abstract

Concrete is a composite building material made from a combination of coarse aggregate, fine aggregate and cement paste which is very often used in the building and construction sector in Indonesia. The increase in the use of concrete causes the amount of available resources to decrease, so that one alternative that can be used to overcome this is to utilize the results of industrial waste as a substitute for concrete constituents. The purpose of this study was to determine the composition and results of the compressive strength of concrete using substitution materials in the form of oil palm shells and fly ash. The percentage variations used are 0%, 3%, 6%, 9% for oil palm shells and 5% for fly ash in each mixed plan with a design concrete quality of K-200. The number of test objects is 9 cubes per mixed variation with a test age of 7 days, 14 days and 28 days. such as for village roads, ground floors and column foundations.
