Concrete slab: thickness and reinforcement

zingo · 2021-04-14T12:38:14+00:00

Planning to pour a concrete slab on which a stone oven (approx. 800 kg) will stand. The slab will be supported by a frame of concrete pillars (approx. 80 cm high), possibly an additional row in the middle if needed. What thickness should the slab be? And how strong of a reinforcement mesh do I need? Is it better to have two "layers" of reinforcement rather than one? I would prefer to avoid the row of pillars in the middle. Can I skip it, or is it needed?
