HTH-450 High Strength Concrete Compressive Strength Test Hammer

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

Parameter:

Test range	20~110Mpa
Standard impact energy	4.5J (kgf. m)
Impact spring stroke	100mm
Impact spring work length	160mm
Impact stroke	100mm±0.5mm
Tension spring rigidity	900±40N/m
Calibration value on test anvil	88±2
Sphere radius of impact pole	SR35mm
Size	ф54×350mm
Weight	1.28KG

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) ℃.
