PROBLEM TO BE SOLVED: To utilize byproduct slaked lime as a landfilling material having sufficient strength without exerting an adverse effect on environment. SOLUTION: In this landfilling method using byproduct slaked lime, first, carbide slag being byproduct slaked lime is mixed with blast furnace slag to obtain a mixture (step 101). Herein, since this carbide slag is produced in a wet manufacturing process for manufacturing acetylene in a slurry form, it is unnecessary to add water newly. Next, the mixture is solidified by hydration reaction to manufacture an improved body (step 102). By this constitution, the carbide slag is cured by the latent hydraulicity of blast furnace slag to be modified to the improved body having sufficient strength. Subsequently, the cured improved body is aerially aged to be carbonized (step 103). Next, the neutralized improved body is charged in a closed sea area as the landfilling material (step 104).
