Massive production of andesite natural stone causes environmental problems due to the large amount of powder waste produced. Andesite stone contains a high percentage of SiO2 which indicates its possibility to be used as a mineral additive for concrete. Research that has been conducted by researchers from various countries shows that andesite stone has fine grains with a specific gravity of 2.66 - 2.68, Loss on Ignition 2.37 - 3.38, has a content of SiO2+Al2O3+Fe2O3>70% which can be classified as fly ash type F based on ASTM 618-92a. The use of andesite stone powder waste as a partial replacement of cement in concrete showed that concrete properties improved at an optimum of 10% at 28 days and 90 days of concrete age, respectively. The use of andesite waste powder in larger quantities showed a decrease in concrete properties. The use of andesite powder waste in concrete is recommended to reduce the impact of waste on the environment as well as to reduce the use of cement in concrete as an effort to support sustainable and more environmentally friendly construction.
