Concrete test hammer manual

portability, the Concrete Test Hammer is widely used in civil engineering and construction industry for testing the strength of concrete. Compared to other nondestructive testers, the Concrete Test Hammer is an economical and practical nondestructive testing instrument. HTA is a medium Concrete Test Hammer, its kinetic energy of impact is. Correct Use of the Hammer Use the grinding stone to smoothen the test surface. Perform a few test impacts with the concrete test hammer on this smooth, hard sur - face before taking any measurements which you are going to evaluate. Perform a consisten-cy check on the test anvil. The number of test impacts required for a valid. Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing. The operation of rebound hammer is shown Estimated Reading Time: 8 mins.

Concrete Test Hammer, Surface Hardness The hammer is intended for testing the quality of concrete in finished structures such as buildings and bridges. Supplied complete with carrying case and carborundum stone, the hammer is suitable for testing concrete with compressive strengths of 10 to 70 N/mm2. This manual contains important information on the safe usage and maintenance of UTC Concrete Test Hammer (Schmidt Hammer) N Type and of its related components. Please read through the manual carefully before operating the device for the first time and keep it for the future reference. Liability. The manual concrete test hammer, aka rebound hammer, schmidt hammer, swiss hammer, sclerometer, is the most widely used non destructive instrument for compressive strength determination. However, it typically has the largest coefficient of variation; therefore its result should be verified with another non destructive test such as the V-Meter MK III.
