How thick should concrete be for a garage floor?

The concrete slab should be four-inches thick at least; it needs to be thicker if heavy equipment will rest on it. Building codes offer requirements for the concrete mix, which vary by region. The standards are expressed in terms of “compressive strength,” which boils down to the amount of water used in the mix.

What is 4000 psi concrete used for?

4000 PSI concrete is used for heavy traffic pavement, heavy use floor slabs like shops and warehouses, and concrete footings designed to support heavy loads.

What is 5000 psi concrete used for?

Used in special construction applications, including some large-scale commercial and industrial properties, 5,000 PSI can withstand heavy impact and extreme wear and tear.

What is the best concrete mix for a garage floor?

The best combination would be 1 part cement, 2 parts sand (small aggregates), 3 parts gravel (large aggregate) and 1 part water. Mix all the dry materials first, and slowly add water as you go along. Mix all of these thoroughly together until the lumps disappear.

Does higher PSI concrete crack less?

adding more cement increase the psi and its more resistance to bending by load factors, less cracking.
