Abstract
In the construction sector, new demands for aesthetics are increasing due to structural stability and improvement of living standard and consciousness level. On the other hand, Red Mud sludge is generated from aluminum hydroxide extraction process from Bauxite. Red mud sludge contains about 20% of $Fe_2O_3$ and represents a natural reddish brown. It is highly applicable to the construction industry. In this paper, red mud sludge with a water content of 50%, which is a by - product of the industry, was prepared as a liquid phase. The liquefied red mud was added to cement mortar and the strength and color difference of cement mortar were investigated according to the addition amount of liquefied red mud. As a result, the compressive strength decreased with increasing amount of liquefied red mud. The color of cement mortar containing liquefied red mud was found to be distributed in the range of YR series in all samples. As the amount of liquefied red mud increased, the color became darker.
