Neoprene pads flow under compression to fill irregularities in cylinder ends and assure load uniformity. Pads for 4in (102mm) and 6in (152mm) diameter specimens comply with the latest version of ASTM C1231.
50 Durometer Pad: Design strength 1500 to 6000 psi.
60 Durometer Pad: Design strength 2500 to 7000 psi. 70 Durometer Pad: Design strength 4000 to 7000 psi.
Neoprene Pads are sold singly. Two are required for compression testing of concrete cylinders. Model numbers with ending in "CS" of 4in and 6in Neoprene Pads specify case quantities of 12 pads at reduced per-pad price.
Quick Release Polysaccharide powder is a lubricant and bond breaker that extends pad life, allows more consistent test results, and promotes easier change-out of pads. For quick release of pads from Unbonded Capping Set Caps, HM-277 Kit includes 8oz of powder in a Shaker Dispenser and 48oz of refill powder. Order additional filled Dispensers or Powder Refills in packs of two.
