In this article we will review the potential options and practical solutions for on site evaluation of concrete strength Concrete compressive strength is by far the most important property of concreteThe theoretical compressive strength of concrete is eight times larger than its tensile strength This implies a fixed relation between the compressive and tensile strength of concrete In fact there is a close relation but not a direct proportionality The ratio of tensile to compressive strength is lower for higher compressive strengths

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well The most common method is to use cylinder cores drilled off the structureReinforced concrete has a compressive strength in the region of 4 000 psi and steel in the region of 25 000 psi But in a typical concrete structure the compressive load is borne by the bulk concrete

51 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materialsPortland cement concrete less than a year old has compression strength of 1 000 pounds per square inch psi and tension strength of 200 psi Concrete more than a year old has compression psi of 2 000 pounds and tension psi of 400
