Concrete compressive strength can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in commercial structures. Some

Testing the Compressive Strength of Concrete — What,

When strength test results indicate that the concrete delivered fails to meet the requirements of the specification, it is important to recognize that the failure may be in the testing, not the concrete. This is especially true if the fabrication, handling, curing and testing of the cylinders are not conducted in accordance with standard procedures. See CIP 9, Low Concrete Cylinder Strength.

The compressive strength of the concrete and concrete testing is must known information in structural design. Compressive strength is initially checked by doing mix design to make sure the grade of concrete considered in the structural design is achieved. Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete.

Compressive Strength Test of Concrete Civil

Compressive strength as a concrete property depends on several factors related to quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common]. For example, as per ASTM C39, a standard test method is given to get the compressive
