The rebound hammer is first calibrated.
. 1 The rebound hammer is tested against the anvil made of steel having a. REBOUND HAMMER TEST 10 ABSTRACT The aim for this experiment is to determine the rebound number of hardened concrete to assess the uniformity of concrete in. An intact specimen of very hard rock breaks only by.
Reliance Engineering Consultancy Pvt. Gradually push the instrument toward the test. The impact energy required for rebound.
To find the quality of concrete in relation to standard. Rebound Hammer Test. The reliability of the rebound hammer test has been investigated in this paper.
This test is very widespread in practice because it is a simple nondestructive fast and cheap technique but. Discuss the limition or affect the. Apparatus consists of a spring controlled mass that slides on a plunger within a tubular housing.
The issue of concrete strength often arises in civil engineering practice. Hold the instrument firmly so that the plunger is perpendicular to the test surface. The Rebound Hammer test has been around since 1940s and today is a commonly used method for estimating the compressive strength of in- place concrete.
