## Compressive Strength of Concrete | Definition,

Concrete's compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000psi (28 MPa) and higher in commercial structures. Higher strengths up to and exceeding 10,000 psi (70 MPa) are specified for certain applications. Importance of Determining the Compressive Strength: Compressive strength results are primarily used to determine that the concrete mixture,Characteristic Strength Of concrete - Engineering,The classification of concrete grades is based on their compressive strength. Each concrete grade e.g. C30/37 is characterized by two equivalent strengths, which in this specific example are 30 MPa and 37 MPa.
