Özet

The liquid limit is one of the most commonly used index properties of soils. The study compares liquid limit values determined by the hard base and soft base Casagrande apparatus and the cone penetrometer, based on 42 natural soil samples with liquid limits varying between 30 and 105%. The results indicated that the liquid limits obtained by the soft base Casagrande apparatus are up to 5% higher than those from the hard base apparatus. Compared with the cone penetrometer, the hard base Casagrande apparatus generally gives a lower liquid limit for soils with a liquid limit of less than about 70% while the soft base Casagrande apparatus gives a higher liquid limit for soils with a liquid limit of more than some 40%.
