Apply light pressure on the plunger and allow it to extend to the ready position for the test.

. Soil Classification Lab 1. To find the quality of concrete in relation to standard requirement. Assessing the conpiessive strength of conci ete with the help of suitable corelations between rebound index and compressive strength.

A Schmidt hammer also known as a Swiss hammer or a rebound hammer or concrete hammer is a apparatus to measure the elastic properties or strength of concrete or rock mainly surface hardness and penetration resistance. The following are the Rebound hammer test methods available in our lab. Rebound Hammer Test.

To carry out this experiment apparatus like rebound hammer is needed. Rebound Hammer was invented by Ernst Schmidt a Swiss engineer. Up to 3 cash back LAB MANUAL Rebound Hammer - Free download as Word Doc doc docx PDF File pdf Text File txt or read online for free.

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 situ and to identify the areas of poor quality concrete. Hold the Rebound Hammer at right angles to the test surface with the plunger pin pointing towards the test location Push the plunger against the concrete and force the cylinder body towards the concrete. The basic features of this equipment are shown in Figure 1 below.

This test is very widespread in practice because it is a simple nondestructive fast and cheap technique but not enough attention is paid on its reliability. The rebound hammer strength test being a non-destructive test. Apply a gradual increase in pressure until the hammer impacts.

Technical Report on Schmidit Hammer Test. Rebound Schmidt Hammer 1. The force causes the latch.

Test of hardened concrete -Non destructive test Rebound hammer Objective. Assessing the likely compressive strength of concrete. Introduction The rebound hammer test is the most popular method to measure the surface hardness of a concrete mass.

Rebound hammer is a spring-loaded steel hammer that when. The reliability of the rebound hammer test has been investigated in this paper. The Swiss engineer Ernst Schmidt first developed a practicable rebound test hammer.
