Deslauriers 3in. Compression Pad- 50duro
The Deslauriers Neoprene Compression Pad flows into irregularities and distributes the test load uniformly without creating air pockets to assure consistent breaks. Neoprene Pads are accurate, efficient, and economical for compressive strength tests of concrete cylinders and serve as a faster and safer alternative to sulfur capping. Compression Pads are available 6in, 4in, 3in, and 2in diameter cylinders. Select a durometer rating based on the design strength of the concrete specimens.
Pad Re-use:
Per ASTM C1231, the pad can be reused up to a maximum of 100
times. But Cautions that:?Pad life depends on the hardness and type of
pad material, the strength of the concrete, the difference between the
outside diameter of the cylinder and the inside diameter of the
retaining ring, the unevenness and roughness of the ends of the
cylinder, and other factors. Based on available information, scuffing or
abrasion of the perimeter of the pad is normal, provided it does not
reduce the thickness of the pad around the perimeter. Cracks or splits
in the pad are reported to materially reduce cylinder strength. Replace
pads which have cracks exceeding 3/8 in. in length, regardless of
depth.?
