I’m not an expert when it comes to this. Didn’t even know this was possible. Useful read, appreciate your posting this.

Saw cuts and rebar have nothing to do with each other. Rebar pneverts failure from weight being applied to the top of the slab. Concrete is only strong in compression, meaning a crushing force. It is very weak in tension, meaning a pulling force. When a load is applied to the slab, the top is under compression while the bottom is under tension. When the bottom fails from tension, the crack spreads upwards to the top. This happens when the ground under the slab settles, leaving a void. Rebar is meant to prevent the crack from continuing to the top of the slab, creating two separate pieces. Wire mesh does the same thing. That’s why reinforcing should always be in the bottom 1/3 of the slab, not near the top. It’s like bending a piece of wood; it always starts to break on the convex side, not the concave side. Saw cuts are used to prevent surface cracks. They are not structural, they just don’t look good. These happen because the concrete creates heat through a chemical process. The heat rises to the top, drying the surface more quickly than the interior. The differing rates of dehydration and cooling create tension, making cracks. Saw cuts create weak points in the slab, which will release the tension first. They are meant to hide the cracks that would normally look jagged in the bottom of the straight line. Filling the saw cuts with caulking won’t affect how the relief cuts perform, but it will keep debris out of them. For a 10 25 pad, you could probably get away without the cuts. I build factories for a living, and supervise the concrete finishers. We usually cut the slab into 12 6″ x 12 6″ squares, but that would only mean one joint in your case. I can’t speak for a stamped finish, though. This should settle the question of relief cuts vs. rebar, though. They do two different jobs.BTW, all concrete needs rebar, wire mesh, or fiberglass mesh. Plain concrete without any reinforcing will break into pieces under its own weight. Fiberglass mesh is added to the concrete at the plant.
