What is the best slump for concrete slab?
A good slump for most flatwork placed by hand: five inches. For slabs struck off with mechanical equipment: two to four inches.
How many yards of concrete do I need for a 24×24 slab?
7.11 yards
For example, for a concrete slab that is 24′ X 24′ X 4”, simply enter 4 in the Thickness/Depth field, 24 in the Width field, and 24 in the Length field. Click “Calculate”.

How thick does a concrete slab need to be for a garage?
four inches thick
