According to the Swiss standard SN 670 321a the Schleibinger

plates on top and the bottom size of the specimen. With a high precision
LVDT the height change
of the specimen during freezing and thawing is measured. The test
comines two test methods: The height change test and the strength
weakening during the thawing process. The test is easy to handle and is
finished in 5 days. The specimen has an optimal water content,
determined by the Proctor test.
