A technique for long-term storage of clay samples

This note describes a technique for sealing and storing clay samples so as to prevent aging effects during long periods of storage. It also gives the results of a study carried out on samples stored from 3 to 8 years, which prove the efficiency of that technique; the liquid limits, the liquidity indices, and the pH values remained constant during these long periods of storage. Key words: sensitive clay, storing, sealing, aging.
