Rebound hammer - Concrete

Rebound hammer. The rebound (Schmidt) hammer is one of the oldest and best known methods of comparing the concrete in various parts of a structure and indirectly assessing concrete strength. It is actually a measure of surface hardness. The rebound hammer should be considered as a means of determining variations of strength within a structure ...

28/10/2014· A Schmidt hammer is a device to measure the elastic properties or strength of concrete or rock. Today Schmidt hammers are in use throughout the world for estimating strength of concrete. The European standard for Schmidt hammer testing is EN 12504-2. The test hammer hits the concrete with a spring-driven pin at a defined energy, and then ...

The splittance of a graph | SpringerLink

The splittance of an arbitrary graph is the minimum number of edges to be added or removed in order to produce a split graph (i.e. a graph whose vertex set can be partitioned into a clique and an independent set). The splittance is seen to depend only on the degree sequence of the graph, and an explicit formula for it is derived. This result allows to give a simple characterization of the ...

Schmidt hammer test or Rebound Hammer test of Concrete

5/8/2018· To do this, the Schmidt hammer is tested against the Steel test anvil which has a Brinell hardness number of about 5000MPa. Clean the surface of concrete, ensure the concrete is clean and dirt free. As mentioned in the Operation of Rebound hammer, it involves four stages in the first stage the hammer is held at right angles to the Concrete Surface of structure for finding the rebound number.
