Premixed concrete comes in 5 standard strength grades. The 20mpa is the minimum strength grade that must be used and suffices for most domestic works like floor slabs, sheds, and paths. If you are building driveways, patios, and paths that attract heavy traffic, 25mpa grade is preferred. 32mpa is the highest grade used in domestic projects, usually for places that require high strength like car parking and suspended slabs. The highest two grades, 40mpa and 50mpa, are used specifically for high buildings.
