Capping retainers (couple) for Ø 150x300mm and 6'' x12'' cylinders.
Used for compression tests on concrete cylinder specimens, as an alternative method to the sulphur capping and grinding machine.
Two steel capping retainers are applied on the two flat surfaces of the cylinder.
Two neoprene pads are put between them, for a better load distribution.The system is not applicable for expected strength lower than 10 Mpa.
Note: the couple of retainers + neoprene pads have a total thickness of 46 mm. Therefore the testing chamber of the press must have more vertical clearance than the height of the specimen + 46 mm.
