Q&A

Compressometer/Extensometers measure deformation and strain for MOE determinations, plus the horizontal extension of the sample to calculate Poisson’s ratio. An additional yoke assembly attached to the test specimen allows the measurement and calculation of both properties. These units integrate with the “MR” versions of Gilson Automatic Compression Machines.

ACA-640 is designed for use with 4x8in concrete cylinders.

ACA-660 is designed for use with 6x12in concrete cylinders.

Product Q&A

Q: How are longer specimens extracted and the piston returned?

Specimens longer than 5in are extracted by repositioning the Adapter Ring after maximum piston travel, and the spring-loaded piston automatically returns to the start position when the release valve is opened.
