Due to customer requirements Proceq have re-introduced the pendulum rebound hammer OS-120PM specifically for the testing of mortar joints in brickwork.
Mortar testing is difficult to undertake on site and joints are often too thin to enable sufficient or unbroken sample for laboratory testing. The pendulum hammer has a specially developed plunger shaped to apply impact to the surface of the joint.
Based upon rebound values the quality of mortar can be assessed from ‘Excellent to Poor’.
The Proceq test hammers are industry recognised, robustly constructed and widely used portable NDT measuring devices for the site assessment of material condition.
The pendulum hammer is now part of our extensive NDT hire range. Included in our NDT range is the James Windsor Pin apparatus. The Windsor Pin remains an accepted strength assessment tool utilizing the principle of resistance to penetration. Using a spring loaded gun a hardened steel pin is driven into the mortar. Depth of penetration correlates to compressive strength. Recommended practice is to take seven readings – discard the high and lowest and use the five resultants to determine a mean and the corresponding strength.
The pin is reusable, in the order of six times before replacement is necessary.
