The best illustration of the strength differences between stone floor slabs and steel reinforced concrete is in their demolition. Some sections of the existing aisles are already steel reinforced concrete. Probably from previous restoration efforts. The video below shows the demolition of a small section of one of those concrete slabs.
As you cans see it takes several hits to loosen the concrete from in between the reinforcement and those pieces are rather small. By contrast the video below shows the demolition of the next section of the aisle which is stone.
