Solidification of Oyster Shells Used as Cadmium Ion Removal Material with Portland Cement
This research investigated the soiJdification of oyster shell (Crassostre commercialis) used as Cd2+ removal material with Portland cement by varying the oyster shell/Portland cement ratio and curing time. Leachability of Cd2+ was determined with Toxicity Characteristics Leaching Procedure (TCLP)....

| Summary: | This research investigated the soiJdification of oyster shell (Crassostre commercialis) used as Cd2+ removal material with Portland cement by varying the oyster shell/Portland cement ratio and curing time. Leachability of Cd2+ was determined with Toxicity Characteristics Leaching Procedure (TCLP). The expel trnental result demonstrated that the optimum condition for oyster shell/Portland cement ratio was 4. After curing time for 7 d, densities of solidified oyster shell (OS-A) as well as bu rn ed oyster shell (OS-B) were 1.87 and 2.15 ton m-3, respectively. Unconfined compressive strength of solidified OS-A and OS-B were 69.7 and 134.5 kg cm-2, respectively Cd2+ in leachates of solrdified OS-A and OS-B were 0.45 and 0.73 mg L-1, respectively, and less than 10 mg L-1.
