Oedometer tests were performed on one clay and one marl reconstituted at various initial water contents and consolidated from slurry-like form, in order to investigate the properties of Intrinsic Compressibility and the Intrinsic Compression Line. The properties of Intrinsic Compressibility are found to be very ‘robust’ relative to the initial water content of the slurries. It is also shown that the relationship between Void Index and the logarithm of vertical stress providing the Intrinsic Compression Line can be derived analytically. Finally the time-settlement curves were studied and oedometer tests with reduced time intervals between changes in load were performed in order to study the differences in the values of the properties of Intrinsic Compressibility obtained from the two kinds of tests.

This parameter can be determined by carrying out laboratory oedometer test on undisturbed samples. However, the test is quite time consuming and expensive. Therefore, this study aims to correlate this parameter with the index properties. For this purpose, compression index and index properties values for the analysis and calculations were sought out from existing journals. Simple and multiple linear regression analysis were performed in SPSS software for the prediction. Compression index shows a good linear relationship between liquid limit, plastic limit and specific gravity
Storing contaminant soils, such as dredge materials, sludge and mine tailings, and reclaiming contaminant soil storage areas back into the economy has arisen as an important economical and environmental problem in today's world. The scientific studies in the last thirty years have revealed critical new information regarding the deformation behavior of high water content soils. In this article relationships between material properties used in constitutive models for self-weight and/or surcharge loaded high water content (slurry) clays and their index properties are investigated. For this purpose three different kinds of clays in a slurry consistency are subjected to seepage induced consolidation in an experimental setup. Information obtained from these experiments, together with information already in literature, is used to investigate the relationships between the index properties and the consolidation constitutive model parameters. The relationships obtained from the experiments are then utilized to predict the self-weight consolidation of Halic (Golden Horn) dredge materials. These predictions are then compared with the results of numerical analysis and found to be in good agreement.

Compression behavior of reconstituted clay: A study on black clayThe soft and black clay found in the Kathmandu Valley is locally known as Kalomato which is highly compressible and weak. The Kalomato from the Khasibazaar is taken as study material. Experimental study is carried out on undisturbed, remoulded and reconstituted soil samples to determine the compression behavior. The study revealed that the undisturbed soil sample has the highest compression index among all samples while the remolded sample has the lowest compression index. The reconstituted soil sample using cement shows that the compression index increases with the increase in cement content while decrease with the increase in curing time. When cement content increases to 15%, the load required to compress the soil to the equal void ratio also increases to almost three times of the undisturbed soil and seven times of the remoulded soil. Therefore, reconstitution of soil using cement is found as effective method for improvement of compression behaviour. This study also has estab...
