UNBONDED CAPPING PADS AND RETAINERS

Category:

STANDARDS: ASTM C1231 | AASHTO T22, T851
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 neoprene pads are available in two models:
– 60 shore hardness pads for expected strength from 10 to 48 MPa
– 70 shore hardness pads for expected strength over 48 MPa
The system is not applicable for expected strength lower than 10 Mpa
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.
