The 2in (50.8mm) Neoprene Pads are 0.5in (12.7mm) thick and available in 50 or 70 durometers. They are used for compressive strength testing of 2in concrete cylinders. The pads flow during compression to fill irregularities in cylinder ends and ensure load uniformity. The 2in Steel Retainer Set is purchased separately and has two rings to hold one pad at each end of the concrete cylinder. Each pad can be used for up to 100 tests, and two pads are required for a single test. Each of these models can also be used with 2.125in (54mm) dia. rock cores.
The 2in, 50 Durometer Pads work well in testing concrete strengths from 1,500-6,000psi (10-40mPa).
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
Sold individually. Two are required for compression testing of concrete cylinders. Choose 12 for one box.
Per ASTM C1231, the pad can be reused up to a maximum of 100 times.
