- •
Consolidation parameters depend upon overburden pressure, mineralogy and pore water chemistry.
- •
Bentonites consolidate faster in the presence of salt solution in comparison to water.
- •
Cc, mv and t90 of the bentonites decreased whereas cv increased with the increase in salt concentration.
- •
cv decreased whereas t90 increased with the increase in the overburden pressure.
- •
Bentonite with higher liquid limit and swelling capacity exhibited higher values of t90, mv and Cc.
