Cation exchange capacity (c.e.c.) determined by methylene blue can be regarded as a useful soil mechanical test in its own right. When a large number of liquid limit (LL) tests have to be done to determine variation in clays of the same general type, as on an engineering site~ economy of operation could be achieved by carrying out many c.e.c, tests and few LL tests. It is only when comparing clays of widely different types that correlation is poor.
