Concrete Test Hammer

Operating Principle

As the concrete hammer rod is pressed against the surface that is to be tested, a spring is loaded. When the rod has disappeared inside the concrete hammer completeley, a mass is automatically released that strikes the rod itself on the internal end and, through this, the surface of the concrete.

The rod reacts and re-transmits the rebound to the mass, the harder and more compact the concrete, the greater the rebound.

During the rebound stroke, the mass moves a pointer that indicates the maximum point of return and at that same time indicates a reference value on the scale.

This number, when translated to the chart on the concrete hammer mechanical 58-C0181/C, gives the compression resistance value in respect to the impact angle.
