Concrete Testing

This simple gauge has been designed to provide inspectors with a low cost alternative to a graduated microscope for determining the width of a crack in concrete or other building materials.

The HT 225A Portable Concrete Test Hammer (HT225A) is designed specifically for the non-destructive testing of concrete structures. This method has considerable advantages over conventional methods of assessing the compressive strength of concrete in that large areas can be tested in a very short time at a very low cost. In addition, it is possible to determine the variation in concrete quality between different sections of a structure. The above standards refer to assessment of the rebound hardness of mortar which is directly related to the compressive strengths of the material being tested.
