Abstract

Abstract : This study uses volcanic ash waste from the eruption of Mount Bromo as a substitution of cement (cementitious) for mixture material of concrete, and observing its effect on physics and mechanic properties of concrete. The mix design analysis of concrete material uses DOE method with the characteristic strength is 300kg/cm2, and w/c factor 0.5. The volcanic ash that is used are 0%, 5%, 10%, 15%, and 20% from the weight of the cement, and have granular size grain number 200. The test that is conducted are compressive strength test, porosity test, and modulus of elasticity test. The test result shows that compressive strength from concrete of volcanic ash waste is 5% and 10% reached the charactersitic strength, even though its under normal concrete for about 2% - 3%. The significant distinction occurs on porosity concrete value with mixed volcanic ash is over 10%, compare to 5% and 10%. The modulus of elasticity test result shows that volcanic ash concrete 10% and 15% shows the better elaticity, compared to normal concrete. Keywords: Concrete, cement, cementitious, volcanic ash
