SOLUTION RETENTION CAPACITY AS AN ALTERNATIVE TO THE SWELL INDEX FOR SODIUM BENTONITE

The paper reports on a solution retention capacity (SRC) test that was developed and evaluated as an alternative to the swell index test (SI) for bentonite of geosynthetic clay liners. The SRC represents the amount of a 50 ml solution retained in one gram of oven dried bentonite after centrifugation at 2750 g and the SRC values are reported in units of mL/g. On the basis of the strong correlation between SRC and SI, the SRC test may be a more useful alternative to the SI test in terms of evaluating the quality of a sodium bentonite or the potential impact of inorganic salt solutions on the bentonite of geosynthetic clay liners.
