What is Schmidt Hammer used for?
A Schmidt hammer, also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance. It was invented by Ernst Schmidt, a Swiss engineer.
How accurate is Schmidt Hammer Test?
Among the NDT and MDT procedures, the Schmidt, or rebound, Hammer test is largely the most commonly used worldwide. The reason for such a success is not the reliability of the tests, that may be easily showed to be less than 30%, but the simplicity of the procedure, the low price of the equipment and its easy of use.
What is the Schmidt Hammer Test?
1. A non-destructive technique used to determine the compressive strength, surface hardness and penetration resistance of reinforced concrete and masonry structures by measuring the rebound of a spring-loaded mass impacting against the surface of the sample.
What is rebound number?
The rebound hammer is a nondestructive testing apparatus, whereby the rebound of the spring driven mass is measured after its impact with concrete surface. The output of the rebound hammer is referred to as rebound number and are correlated with surface hardness of concrete.
What is the rebound hammer test?
What is DT test?
Destructive testing (DT) is a form of object analysis that involves applying a test to break down a particular material to determine its physical properties, such as the mechanical properties of strength, toughness, flexibility, and hardness. Automobile crash tests are a well-known form of destructive testing.
What is rebound index?
The extent of rebound, which is a measure of surface hardness, is measured on a graduated scale. This measured value is designated as Rebound Number (rebound index). A concrete with low strength and low stiffness will absorb more energy to yield in a lower rebound value.
What’s the maximum size of a Schmidt Hammer?
The original Schmidt ® hammer, type N, is designed for non-destructive testing of concrete items 4″ (100mm) or more in thickness, or concrete with a maximum particle size less than or equal to 1.25″ (32mm).
What is the impact energy of a Schmidt Hammer?
It is designed for testing concrete within a compressive strength range of 1,450 to 10,152 psi (10 to 70 N/mm 2) and impact energy of the test is 1.6 ft-lbs (2.207 Nm). The (type N) Schmidt hammer is pressed against the concrete structure and the rebound values are displayed on a mechanical sliding scale.
What was the purpose of the Schmidt concrete test hammer?
Original Schmidt Concrete Test Hammer is the classic analog rebound hammer known for its accuracy, repeatability, and reliability. It provides a rapid, non-destructive method for compressive strength estimates of hardened concrete, concrete uniformity determinations, and assessment of rock hardness.
