Abstract

Red mud is an industrial by-product produced during the manufacturing aluminum hydroxide (Al(OH)3) and aluminum oxide(Al2O3) from Bauxite ores. In Korea, approximately 2tons of red mud in a sludge form with 40~60% moisture content is produced when 1 ton of Al2O3 is produced through the Bayer process. An annual production of approximately 20tons are produced by company K, which is responsible for most of the domestic production. Therefore, in order to utilize Red Mud in the construction industry, this study evaluated the pore characteristics of ordinary portland cement mortar according to the red mud replacement ratio.
