Re: Thickness of concrete vs. mesh size
19 You will notice if mesh is too close to the surface with mesh pattern on the concrete slab showing through, but the actual mesh is not visible.
A mesh layer closer to the surface will help with no cracking.
I like to have 25mm cover min.
In regards to MPa and water.
Its something like 1 water to 2 cement produce 35mpa.
1 water to 1 cement produces 10 mpa.
20kg of cement to 10 litres of water is harder to work than 1:1.
Use water reducers and the mix can be like 2 water for 1 cement but yet its strength can still be 35mpa.
However water reducers add more dimensions to the equation and can be tricky.
Good Luck
