LABORATORY AND FIELD LEACHING TESTS ON COASTAL SALT-BEARING SOILS. DISCUSSION AND CLOSURE

A discussion of a paper with the aforementioned title by Nabil F. Ismael, published in this journal (Volume 119, Number 3, March 1993), is presented. The discussers bring several points to the author's attention: 1) permeability of the saline soil remained constant while total dissolved solids and electrical conductivity sharply declined, 2) wet sieving with distilled water in combination with hydrometer testing resulted in breakup of sand-size particles containing large amounts of gypsum and leaching of highly soluble chloride salts, 3) absence of a cohesion intercept from the results of consolidated undrained triaxial tests on natural sabkha specimens might be attributed to disturbance of the tested soil samples, 4) leaching of soluble salts enhances the collapse potential of cemented sabkha soils rather than its compressibility, and 5) additional research is needed to better understand the behavior and characteristics of saline soils. Discussion is followed by closure from the author.
