Natural resources in the form of aggregate concrete material shaper that is sand, stone and cement, still the chosen one and still be useful although the negative risk to the broken area become enlarge slowly, so that to reduce the useful of sand aggregate and cement. Researcher doing research in order to know the strong value non sand concrete pressure with the cement reduction and replace with fly ash 20%, 40%, 60%, and 80%, until 90 days of the concrete. To get the supporter date, the research method which used is the research to the all material on the building and fly ash mechanic, as well as rough aggregate and strong test concrete pressure at the 7 days, 28 days and 90 days. The result of the research shows that the trial aggregate include in lighten aggregate cause of aggregate specific gravity 2.40 and fly ash specific gravity 2.45. beside, the concrete pressure on 7 days still classified in lighten concrete. However, in the 28 days and 90 days trial, concrete classified as normal concrete with strong pressure more than 17 mpa.
