A ceramic clay brick manufacturing method using crushed powder of waste batteries is provided to reduce the cost of purchasing manganese dioxide used as a coloring admixture in producing ceramic clay bricks of black, dark red, or dark brown color. A ceramic clay brick manufacturing method using crushed powder of waste batteries comprises the steps of: crushing the clay mixture in the size of 0.5~2mm by using a roller crusher, wherein the clay mixture is produced by mixing clay of 70wt.%, sand or soil cement of 20~28wt.%, and crushed powder of 2~10wt.% obtained from the waste batteries as a coloring admixture for bricks; kneading the crushed clay mixture to make the water content at 18~22%, extruding the clay mixture in the shape of a brick by using a vacuum extrusion pug mill, and cutting the extruded clay mixture in the predetermined size; drying the extruded and molded bricks for 30~40 hours in a drying chamber, in order to adjust the water content to 0~5%; and preheating, sintering, and cooling the dried bricks at normal temperature or 1000°C, 1000~1200°C, and 1200°C or normal temperature, respectively in a continuous kiln.
