Econ-O-Cap Unbonded Capping System
.
- An unbonded capping system for compression testing of concrete cylinders
- Safer Cleaner Economical Time Saving Accurate and consistent Eliminates noxious odors
- ECONOCAP System is available in 2", 3", 4" and 6" diameters.
The Retaining Cup retains the compression pad and fits over the ends of the concrete cylinder. ECON-O-CAP Retaining Cup is machined from high alloy steel to the same tolerances as your platens
Steel has minimal temperature variation and no deflection under load.
The high alloy steel resists scratches, eliminating the need for additional machining.
The Compression Pad, made of tough elastomeric material, flows into irregularities and distributes the test load uniformly without creating air pockets to assure consistent breaks.
Compression pads are available in several hardnesses
50 duro 1500 to 6000 psi
60 duro 2500 to 7000 psi
70 duro 4000 to 7000 psi
refer to ASTM C1231 for max uses, qualification test, etc
.
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.”
Meets AASHTO Standard T22-851.
Meets ASTM Standard C1231.
