What is the typical compressive strength of concrete in metric units?
The strength is to be designed by the Engineer depending on the design limitations, part of the structure, loading characteristic and how this structure or structural element is used. For Residential Buildings: 2400psi or 170ksc or 17MPa for Column Footing & Wall Footing 3000psi or 211ksc or 21MPa for Columns, Girders, Beams & Suspended Slabs Other Structures: 3000psi or 211ksc or 21MPa for Road Pavements, Gen. Bridge Parts, General Construction 4000psi or 281ksc or 28MPa for Bridge Coping, Multi-storey buildings & General Construction 5000psi or 351ksc or 35MPa for Bored Piles, Sheet Piles, High Rise Building High strength concrete for high rise structure may reach 150Mpa NOTE: Strength mentioned are compressive strength at the age of 28days. You can find more on strength regulations in the Structural Code of the Country of the client you are designing for.
