It measures the axial strain on a cylindrical concrete specimen placed in and secured by screws to the inner chamber of this compressometer.
It uses a high-sensitivity strain gauge to take strain measurements, and by multiplying a measurement by a certain factor, the amount of strain can be calculated as a numerical value. Contrary to ordinary strain gauges, this compressometer is simple and easy to operate and can be used repeatedly. It cannot, however, be used to conduct breaking tests.
Breaking strength tests can be conducted with the CM-H model, a destructive compressometer. It measures the compression strain similarly to the CM, with a block 10 cm in diameter and 20 cm in length. Both the high-sensitivity strain gauge and cylindrical concrete specimen are provided with coverings to protect them from damage.
This compressometer allows the strain on a wet concrete specimen, taken out right after underwater curing, to be measured. Linked with either the CLL-NA or CLH-MNA load meter, this compressometer can also be used to measure the modulus of static elasticity.
