A related production method for a building block taking steel slag as a raw material is characterized by comprising the following steps: 1) performing hot disintegration on steel slag; 2) crushing steel slag, performing magnetic selection, ball milling and water selection, so as to select iron and obtain the residual tailing slurry; 3) piling the tailing slurry obtained in the step 2) for storage, disposing and coagulating so as to form a coagulum; 4) crushing the coagulum in the step 3), screening to obtain an aggregate with the particle size of 0.5-6 mm; 5) mixing the aggregate in the step 4) with cement, an additive and other lightweight raw material according to the following weight fractions: 65%-75% of the aggregate, 12%-18% of cement, 1%-6% of the additive, and 5%-13% of the lightweight raw material; 6) adding water into the mixed materials of the step 5) and stirring, so as to obtain a mixed slurry; 7) adding the mixed slurry of the step 6) into a die and performing vibrating compaction molding; 8) performing steam curing by high-pressure steam; and 9) stacking for storage. Compared with the prior art, the method possesses the characteristics of strong compressive resistance and high stability.
