PURPOSE: A solid material using red mud and oyster shell, and a manufacturing method thereof are provided to effectively manufacture a road paving material or a building material by recycling the wasted red mud and oyster shell. CONSTITUTION: A solid material using red mud and oyster shell contains 53.95~67.51wt% of yellow soil, 7.98~8.43wt% of red mud, 7.98~8.43wt% of oyster shell, 8.99~12.65wt% of solidifier, 0.21~0.45wt% mineral additive, and 0.89~2.53wt% of blast furnace slag. The manufacturing method of the solid material comprises the following steps: mixing the yellow soil, the red mud, the oyster shell, the solidifier, the mineral additive and the blast furnace slag after pulverizing(S100,S200); high-pressure spraying 3~8wt% of water for 100wt% of yellow soil to the mixture(S300); compress-molding or spread-hardening the mixture(S400); and curing the mixture with moisture(S500).
