Concrete Testing Methods Types of Tests on Concrete

Methods for Testing Compressive Strength of Concrete. 1. Rebound Hammer. When the spring release mechanism works, a hammer deploys, and a plunger is driven into the slab by impact. This distance is measured from the hammer to the concrete surface and is given a value between 10 and 100. A concrete's strength determines by measuring its density.
