This study compare liquid limit values obtained by the Casagrande apparatus, Russian and British drop cone penetrometer. Liquid limit determined for clay samples collected from 10 boreholes at the Cairo-Suez district (north western part of Badr City), Egypt. It is the most important geotechnical parameter used of fine-grained soils. The liquid limits for 40 natural clay samples varying between 27.8 and 69.7%. It is found that the liquid limit determined by the Casagrande apparatus and Russian standard (cone penetrometer) give essentially the same results with a difference of < 5%. It is observed that the values of Casagrande apparatus were generally lower than those obtained by the cone penetrometer with Russian standard. In addition, Casagrande apparatus for some samples, which had liquid limits of more than 60%, give a higher result. The liquid limits determined by the Russian and British standards are not consistent with a difference of < 1%. Besides, the results which determined by the Casagrande apparatus and British standards (BS), provide equivalent values with a difference of < 3%.
