But to get the most strength from the concrete, you have to recognize when it has just the right amount of water mixed in. Too little water and the particles in the mix won't stick together. Too much water weakens the concrete.

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 materials. Values obtained will depend on the size and shape of the specimen, batching, mixing procedures, the methods of sampling, molding, and fabrication and the age, .

Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as watercement ratio, cement strength, quality of concrete material, quality control during production of concrete etc.

Now place the concrete in the void and allow it to cure before releasing the tension on the cables. In this scenario, the concrete's compressive strength is used to aid tensile strength. That's the idea behind posttensioned concrete reinforcement – concrete's inherent compressive strength is used to .
