About This Product
A rebound hammer gives a quick, approximate estimate of concrete strength without breaking the member. The plunger is pressed against a cleaned concrete surface until the hammer mass is released, and the distance it rebounds is read from the scale. The harder the concrete, the greater the rebound. The reading is then matched to the curves on the chart supplied to find the equivalent compressive strength. Students use it to compare surfaces and to see why destructive tests are still needed for exact values. School Lab Equipment India supplies the Concrete Test Hammer across India and can export it to Brunei, Malta, Bhutan, Uruguay and Mauritius.
Frequently Asked Questions
Q1. How does the Concrete Test Hammer work?
The hammer mass bounces back from a plunger pressed against the concrete surface. The greater the resistance of the concrete, the greater the rebound, which is read on a scale and related to the chart supplied.
Q2. What strength range is it suited to?
It is suited to compressive strengths of 100 to 700 kg/cm².
Q3. What is supplied with it?
The instrument comes with a grinding stone for cleaning the test surface and is supplied in a carrying case. Small and big sizes are available.
