Most grinding failures trace back to a bond mismatch, worn tooling, or the way the grinder is being run. Standard metal-bond tooling cuts soft and medium concrete easily. On very hard concrete (compressive strength above 50 MPa, hard aggregate such as flint or chert), standard bonds glaze over and stop sawing within square meters.

This is where most crews get it right - or lose time.

Contractors who skip this stage usually end up redoing the floor.
A: For most jobs, No. Aggregate hardness matters as much as compressive strength. A 35 MPa slab with flint aggregate can be harder to abrade than a 50 MPa slab with limestone.
A: In short, Yes, as a temporary fix. If it re-glazes within minutes, switch to a softer bond.
A: The practical answer is, Sometimes. Higher concentration with a soft matrix is the standard combination.
