HT-225 Concrete Rebound Hammer For Testing The Compressive Strength Of Hardened Concrete By Rebound Method
HT-225 Concrete 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 concrete structures.
Standard:
BS EN 12504-2:2001 Testing concrete in structures-Part 2: Non-destructive testing – Determination of rebound number
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
GB/T 9138-1988 Concrete test hammer
JJG 817-93 Concrete test hammer
