The squares after the rebar are clearly visible on the surface... I assume it's because the rebar has sunk too close to the surface, but the question is whether this will become more or less noticeable if you grind the surface a bit?

Does anyone have a bit more knowledge about this or tips on a solution? I would prefer not to paint or cover the surface...
 
  • Concrete slab with visible reinforcement grid pattern on the surface, likely due to rebar positioned too close.
Is it not just that it burns at different speeds? How long has it been burning in the picture?
 
Hello!

No answer to your question, but feel free to describe how you've achieved such a nice surface.

It is only two days old. I have also been considering that it burned at different rates, but I know that the rebar sank to about half a centimeter from the bottom. I believe this was due to the concrete being too loose. However, I have little experience with concrete casting, so I'm not sure if this is a normal appearance for the time it has been curing.

I have watered the surface a bit to make it stand out more clearly, but the surface was incredibly smooth directly from the form plywood. With a little oil, the surface would look great if only the marks from the rebar would disappear...
