Unbonded Capping Pad And Retainer

• Two steel capping retainers are placed on the flat end surfaces of the concrete cylinder.
• Two neoprene pads are inserted between the retainers and the specimen ends.
• The pads ensure uniform load distribution during compression testing.

The Neoprene Capping System is used for compression testing of concrete cylinder specimens as an alternative to:

• Sulphur capping
• Grinding methods

This system provides a fast, clean, and reusable solution for preparing cylinder ends prior to compression testing.

Standards Compliance :

• Complied as per ASTM C1231

Neoprene pad hardness :

• 60 Shore A

Suitable for expected concrete strength range :

• 10 – 48 MPa

Not applicable for concrete strength :

• below 10 MPa

• Eliminates sulphur melting process
• No surface grinding required
• Improved load distribution
• Reusable components
• Cleaner and safer operation
