ABSTRACT: Strength assessment and improvement of strength parameters are essential to
design the foundation in clay and marine clay. Several studies have been
made in this aspect. Marine clay is also a potential material for use as liner
material to contain landfill leach ate. The applications include use of marine
clay for transforming waste into light weight aggregates and thus create better
environment. The physical parameters such as Atterberg limits, California
Bearing Ratio (CBR) value, dry density, specific gravity, free swell, chemical
properties such as pH value, cation exchange capacity, organic matter content,
calcium carbonate, and mineralogical composition using X-ray diffraction
analysis are studied. The consolidation characteristics, determination of
strength improvement strategies using admixtures at different proportions
are frequently adopted. Commonly used admixtures are lime, limes mixed
with cement, coir, shredded plastics. The consolidation studies are very vital
and play an important role.
