HT-1000 High Strength Test Hammer For Testing The Compressive Strength Of Hardened Concrete Structures
HT-1000 High Strength Test Hammer
Application:
It is used to test the compressive strength of building concrete components, bridge and so on. It is designed specifically for the non-destructive testing of hardened concrete structures. This hammer is suitable for testing strength of tall building structure, bridge and concrete component etc.
Standard:
ASTM C805/C805M-2008 Standard Test Method for Rebound Number of Hardened Concrete
BS 1881 Testing concrete Part 202 Recommendations for surface hardness testing by rebound hammer
BS EN 12504-2:2001 Testing concrete in structures-Part 2: Non-destructive testing – Determination of rebound number
GB/T 9138-1988 Concrete test hammer
JJG 817-93 Concrete test hammer
JGJ/T23-2011 Technical specification for inspecting of concrete compressive strength by rebound method
Parameters:
| Item | Names | Details |
| 1 | Standard impact energy | 9.8J |
| 2 | Test range | 50~80Mpa |
| 3 | Stroke of rebound hammer | 140mm |
| 4 | Average rebound value on steel anvil Rm | 83+/-2 |
| 5 | Friction of pointer slider | 0.4N~0.8N |
| 6 | Tension spring stiffness | 10N/cm |
| 7 | Size | Φ65*486mm |
| 8 | Weight | About 3.5kg |
Features:
1. Pointer slider is outside ring structure, easy to adjust friction, and to assure equal friction between pointer slider and axis.
2. Shell uses super hard aluminums, protect hammer from damage on site work and prolong use life.
3. Center rod uses imported material, high precision and wear proof
