When manufacturing concrete, several mineral admixture is added to improve the basic physical property and durability and to make economical concrete. Such mineral admixture includes granulated blast furnace slag, fly ash, silica fume, etc., and not only the studies about mixing these mineral admixtures but also the studies for the development of new materials have been steadily in progress. The purpose of this study was to investigate the development of concrete durability using rice straw ash. It is used for chloride diffusion coefficient from rapid chloride penetration test and depth of Co2 penetration from rapid carbonation test that was used for the evaluation of latent durability. According to the experimentation result, when replacement ratio of rice straw ash e was increased from 0% to 10%, it was observed that compressive strength of concrete containing rice straw ash was a similar durability of concrete containing silica fume. And durability performance of concrete containing rice straw ash 10% show a excellent compared to concretes containing granulated blast furnace slag 30 % or fly ash 20 %.
