Soft clays, particularly alluvial deposits, are widely distributed over several coastal regions in Japan. Their softness is the main obstacle for using them as construction and foundation materials. In order to improve these inferior clays, a new treatment method using a trivalent cation, Fe^<+3> was introduced. Iron powder was added into a soft clay by various amounts and the mixtures were cured in aerated and unaerated conditions. After various periods of time, tests were performed to measure the change of engineering properties of the treated samples. The main effect of the treatment was found to be the increases in shearing strength and rigidity of the samples due to the bonding between clay particles and trivalent iron ions from the added iron powder. And the mechanisms of these improvements were clarified by studying with a scanning electron microscope and other instruments.
