Unbonded Capping Pad And Retainer

Used for compression tests on concrete cylinder samples, 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.
