<p>The invention achieves efficient manufacture of L-shaped concrete blocks for retaining walls. The concrete block-manufacturing mold comprises a mold base plate and a loading frame for loading the mold base plate, and is configured so that when the mold base plate is loaded on the loading frame, a poured concrete space for molding the L-shaped retaining wall concrete block shape, which has a vertical part and a slanted bottom plate, is formed. The concrete is poured and when a primary curing is performed and the concrete is semi-solidified, the concrete and mold base plate are removed as a unit from the loading frame and a secondary curing (for example, water curing) is performed.</p> |
