The first is the Schmidt hammer test which is a nondestructive test that aims to measure the surface hardness of a mass of concrete by impacting the concrete surface with a specified mass activated by a standard amount of energy, finding the rebound number, and then using it in calculating GetCivil ReadSchmidt hammer or Rebound Hammer test of Concrete .npSagarmatha Lab | Rebound hammer test for concreteRebound Number is the name given to this measured number (rebound index). Low strength and stiffness concrete will absorb more energy, resulting in a lower rebound value. The premise behind the rebound hammer test method is that an elastic mass' ability to rebound is dependent on how hard the concrete surface it strikes is.SpringerAssessing concrete strength with rebound hammer: review ofJul 25, 2013· On site concrete strength assessment via nonVERTEX LANGRY Concrete Rebound Hammer Manufacturer, SupplierFig.1.Operation of the rebound hammer.
