This method is used as alternative to the sulphur hot capping of concrete cylinder specimens. The system consist of two alloy steel cap retainers and two 12.5 mm thick neoprene pads which are in contact with the upper and lower concrete surfaces. The pads even out irregularities, distributing the test load uniformly to ensure reliable strength results. Pads are reusable for many tests.
The total thickness of capping retainers and neoprene pads for dia. 150 mm (6”) specimens is 50-55 mm which has to be added to 300 or 6” specimen height summing to 355 mm approx. Verify the vertical clearance of your compression tester before testing and, in case of difficulty, get in touch with our service dept. to find a solution.
