concrete slab 3d model

A large rectangular reinforced concrete ceiling slab, size 10 meters x 5 meters, thickness 20 cm. The slab is a solid concrete block with one corner completely torn off, creating a large triangular missing section at the corner. The missing corner forms a clean open hole that goes through the entire thickness of the slab. No debris, no rubble, no broken pieces — just a solid slab with a large missing corner chunk. The broken area shows exposed steel rebar sticking out from the concrete. The object should be isolated, clean geometry, architectural visualization style, realistic concrete material, sharp edges on the broken section.
