Unless they're on the ground floor, there's a lot more to consider than just the compressive strength of concrete. If the gold is sitting on a concrete beam, it bends, causing the bottom to be in tension, while the top is in compression. Concrete has really terrible tensile strength, so rebar is installed to keep it together. The load limit of a concrete beam will be significantly less than that of a solid concrete pillar, and depends on the engineering design.
