Chapter 1 - General Description
1.1. Applications
With the merits of simple structure, easy correction, maintenance and repair, and
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.
HT-225A is a medium Concrete Test Hammer, its kinetic energy of impact is
2207J(0.225kgfm)It is extensively used for testing the strength of various concrete
members (slab, beam, column) of normal building strength and bridge.
1.2. Basic principle
When testing the strength of concrete, Concrete Hammer uses a certain elastic force to
transit the impact force of an impact hammer to the surface of concrete, its initial
kinetic energy redistributes, a part of energy in the form of plastic deformation or
residual deformation is absorbed by the concrete, and another part of energy which is
proportional to the surface hardness is transmitted to the impact hammer, making the
hammer resile to a certain height, then the strength of the concrete is derived from the
proportional relation between the height of resilience and the concrete strength
1.3. Structure of Concrete Test Hammer
The Concrete Test Hammer is mainly composed of ip system, value-indicating
system and shell componentIts structure is shown in Fig1 The diagram shows the
state that the impact hammer has nished impact in the test and the pushbutton has
locked the movementie. .retaining state of resilience value
