CAPO-TEST
CAPO-TEST
The CAPO-TEST system is used to obtain a reliable estimate of the on-site compressive strength of concrete on existing structures in accordance with the pullout test method described in ASTM C900, BS 1881:207, or EN 12504-3.
The surface at the test location is ground using a planing tool and a 18.4 mm hole is made perpendicular to the surface using a diamond coring bit. A recess (slot) is routed in the hole to a diameter of 25 mm and at a depth of 25 mm. A split ring is expanded in the recess and pulled out using a pull machine reacting against a 55 mm diameter counter pressure ring. The concrete in the strut between the expanded ring and the counter pressure ring is in compression. Hence, the ultimate pullout force F required to pullout the ring is related directly to compressive strength.
In-situ concrete strength.
- Quality assurance testing of the finished structure.
- Verification of in-place strength if strength of standard-cured specimens fails to meet acceptance criteria.
- Estimating strength of concrete in evaluation of existing structures.
- Evaluation of fire-damaged structures.

Resizing Tool
Load Verification Unit
The calibration of a pull machine is recommended to be verified at least once a year, after servicing or after repair.
The L-30 Load Verification Unit has a working range of 0 to 100 kN and ensures that the load displayed by the pull machine is within 2 % of the actual load, as required by ASTM C900. The load is displayed to the nearest 0.1 kN.
