    Concrete Compressive Strength an overview

    The concrete compressive strength f c and the modulus of elasticity E c were tested according to the Australian Standards AS 1012.9 1999 and AS 1012.17 1997 respectively using a servohydraulic testing machine with a range of 3000 kN.In order to obtain more accurate experimental data the concrete compressive strength and modulus of elasticity were tested on the day of the beam test.

    If the bond strength of the epoxy or epoxy like material is greater than the tensile strength of concrete than if there is a failure it will be a failure of the limits of the strength of the concrete not the epoxy. Epoxy bond strength is typically measured under ASTM D882. Bond strength to concrete is measured under an American Concrete.

    What is the recommended compressive strength of a concrete

    The most desirable strength for driveways varies based on climatic conditions. In broad terms the colder the climate the higher the desired psi. Areas which experience large numbers of freeze and thaw cycles also require a higher psi concrete mix design. The typical concrete strength used for a driveway is in the 3000 psi to 4000 psi range.
