Abstract

The possibility of improving the engineering properties of a marine clay by adding forsteritic olivine is explored. Strength improvement was recorded with ascending values of olivine contents and curing time. An olivine content of 30% was identified as the optimum value to achieve the targeted improvement for all curing durations. Formation of magnesium-aluminate-hydrate and magnesium-silicate-hydrate were found to be the key components responsible for this strength improvement based on morphological and mineralogical analyses. Comparative studies with identical lime-treated marine clay samples revealed that olivine treatment achieved higher mechanical strength and lower hydraulic conductivity relative to lime treatment for a limited curing duration.
