Concrete Test Hammer
In stock
The Non-destructive concrete test hammer kit.
This non-destructive concrete test hammer is used to evaluate the surface hardness of hardened concrete in order to evaluate the strength in various parts of the structure. With an impact energy of 2.207 Nm and a measurement range of 10 to 70 N/mm2 this product comes complete with a carry case, grinding stone and instruction manual.
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.
Standards
