4in Unbonded Capping Neoprene Pad Cap, 60 Durometer (12/Pk)

4in Unbonded Capping Neoprene Pad Cap, 60 Durometer (12 Pack)

Concrete Cylinder Compression Testing: Neoprene Pads and Accessories

Proper compression testing of concrete cylinders requires two Neoprene Pads to ensure accurate results. These pads are essential for achieving uniform load distribution and meeting testing standards.

4in Neoprene Pads for Compression Testing

Our 4in (101.6mm) Neoprene Pads are designed for compressive strength testing of 4x8in concrete cylinders. They are available in three levels of hardness—50, 60, and 70 durometer—to accommodate different concrete strength ranges. These pads comply with ASTM C1231/1231M and AASHTO T22 standards.

Key features:

• Thickness: 0.5in (12.7mm)
• Reusable: Can be reused for up to 100 tests in compliance with ASTM C1231 standards.
• Functionality: Pads flow during compression to fill surface irregularities on cylinder ends, ensuring balanced and consistent load application.
• Packaging: Sold individually or in packs of 12 for added convenience.

Durometer Options and Strength Ranges:

• 50 durometer: For design strengths of 1,500 to 6,000 psi
• 60 durometer: For design strengths of 2,500 to 7,000 psi
• 70 durometer: For design strengths of 4,000 to 12,000 psi
• 90 durometer: For high-strength concrete exceeding 12,000 psi

Steel Retainer Sets

To properly secure the Neoprene Pads during testing, a 4in Steel Retainer Set is required. This set contains the pads at each end of the concrete cylinder, preventing movement and ensuring consistent results. Retainer sets are sold separately.

Why Use Neoprene Pads?

Neoprene Pads are a practical alternative to traditional capping methods like sulfur or high-strength gypsum mixes. They save time and reduce labor by eliminating the need for messy preparation, while still providing reliable and repeatable results. Additionally, their ability to conform to cylinder irregularities minimizes potential errors in strength readings.

Test Standards Met by Neoprene Pad Caps:

• ASTM C1231/1231M: Standard practice for use of unbonded caps in compression testing.
• AASHTO T22: Standard method for compressive strength of cylindrical concrete specimens.

Benefits of Using Neoprene Pads:

• Cleaner and faster setup compared to traditional capping compounds.
• Reusable for up to 100 tests, ensuring cost efficiency.
• Flexible options for various concrete strength ranges with multiple durometer ratings.
