Liquid limit determination of the high plastic clays by one-point method

The high plastic clay is important material for preparation of sealing coats. The sealing coats are one of part in the waste disposal remediation. The classification of soils represents the first step towards further investigations of clays. Clay is classified using Atterberg's limits or plastic limits. It has been proved that the consistent state of the clay is functionally related to the moisture content. The liquid limit can be represented as a function of any other moisture and the respective number of bumps of the bowl of the Casagrande apparatus at that moisture. This paper proves the existence of that relation that is, however, the property of a certain classification group of materials for which it is necessary to determine the function exponent in the first place and subsequently to perform tests by the one-point method. The existing exponents from other Standards do not have to yield correct results.
