Title: LEACHATE GENERATION FROM RAW AND CEMENT STABILIZED PHOSPHOGYPSUM
Accession Number: 00713584
Record Type: Component
Availability: Find a library where document is available Abstract: The results of a study to determine the leaching characteristics of portland cement stabilized phosphogypsum mixtures developed for base course applications are presented. The study used the Environmental Protection Agency Toxicity Characteristics Leaching Procedure to investigate leaching of mixtures prepared using two cement contents, four cement types, and two levels of relative compaction. The stabilized mixtures were cured 28 days before testing. The results generally indicated higher levels of leaching for the stabilized mixtures for the metals investigated compared with the raw phosphogypsum. Increased relative compaction tended to reduce leached amounts. Type I portland cement usually resulted in increased leaching compared with Types II, III, and V.
