    Methods For Testing Compressive Strength of ConcreteCombined Methods of Strength TestingChoosing A Compressive Strength Method1. Rebound Hammer or Schmidt Hammer (ASTM C805) Method: A spring release mechanism is used to activate a hammer which impacts a plunger to drive into the surface of the concrete. The rebound distance from the hammer to the surface of the concrete is given a value from 10 to 100. This measurement is then correlated to the concretes’ strength. Pros: Relatively easy to use and can be done directly onsite. Cons: Pre-calibration using cored samples is required for accurate measurements. Test
