HTH-450 High Strength Concrete Compressive Strength Test Hammer
Brief introduction:
A test hammer impacts, with a predetermined amount of energy, a
steel plunger in contact with a surface of concrete, and the
distance that the hammer rebounds is measured .
Along with the development of construction! high building
skyscraper becomes more and more, application of high strength
concrete also becomes more popular in the future, which needs a
special test hammer to test high strength concrete. HT-450 test
hammer was developed from HT-25, used to/ test high strength
concrete, and test range is 20-110MPa. HT-450 test hammer is used
to test high strength concrete compressive strength like high rise,
bridge. And apply to C50-C100 concrete

Technical requirements:
1.The instrument measuring rebound value must use energy 4.5J test hammer. The rebound hammer impact length is 100mm. The spherical radius of top of rebound pole is 18mm. The test hammer must have certification of manufacturer and detection institution. It must have product name, type,manufacturer name or brand, manufacturing number and date of production.
2. Test hammer must confirm following standard status: ①Horizontal impact. When impact unhooking, the impact energy must be 4.5J,. ②When the hammer impact the impact-pole, impact spring should be free status, and impact-hammer at the position of 0 point. ③On a test anvil of HRC 60+/-2, calibration value should be 88+/-2.
3. Work temperature of the test hammer should be (-4+40) ℃.
