civilengineerspk.comrebound values. Concrete should be tested only after it has thawed. 6.3.2 The temperatures of the rebound hammer itself may affect the rebound number. NOTE 3—Rebound hammers at − 18°C (0°F) may exhibit rebound numbers reduced by as much as 2 or 3.6 6.3.3 For readings to be compared the direction of impact,

www.screeningeagle.comNote: When using a rebound hammer to estimate in-situ compressive strength, the reference curve(s) provided by the manufacturer must be used with some caution. The correlation between rebound number and compressive strength is very much dependent on the concrete mixture under test. Details on the derivation of reference
