  • Concrete Compressive Strength

    Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in commercial structures. Higher strengths up to and exceeding 10,000 psi (70 MPa) are specified for certain applications.

  • Relation Between Compressive and Tensile Strength of Concrete

    Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the watercement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more ...

  • Measuring Compressive Strength Precast concrete

    The compressive testing process. A concrete compressive strength test machine works by progressively applying force on a specimen. Because strength is defined as the maximum load carried divided by the average crosssection area, the most logical way to determine the strength of a specimen is to load it until it fails.
