6in (152.4mm) Neoprene Pads come in 50, 60, or 70 durometer. They are used when testing compressive strength of 6x12in concrete cylinders and meet ASTM C1231/1231M and AASHTO T 22 standards. The pads are 0.5in (12.7mm) thick and flow during compression to fill irregularities in cylinder ends and ensure uniform load distribution. The 6in Steel Retainer Set are sold separately and required to hold the pads at both ends of the cylinder. Two pads are required. Pads are sold singly or in a package of 12, and can be used up to 100 times.
The 6in 60 Durometer Pads for testing concrete strengths of 2,500-7,000psi (17-50mPa).
Compression pads are available in several hardnesses.
- 50 duro for design strength 1500 to 6000 psi
- 60 duro for design strength 2500 to 7000 psi
- 70 duro for design strength 4000 to 12000 psi
Two are required for compression testing of concrete cylinders.
Meets Test Methods:
