Abstract

Waste gypsum is produced about 2.6million tons per year as a by-product in the process of TiO$_2$production. Geotechnical properties such as natural water content, specific gravity, Atterberg limits were determined to figure out the engineering characteristics waste gypsum. Grain-size distribution, compaction, CBR tests, and unconfined compression test for various mixing ratios between waste gypsum and decomposed granite soil 8t dredged soil. The environmentally adverse effect for mixed specimen with waste gypsum is far below than those of regulatory requirement.
