Physico-chemical and biological characterization of urban municipal landfill leachate

Experiments by three methods to determine the swelling pressure of clays showed that the conventional consolidation test gives an upper bound value, the method of equilibrium void ratios for various consolidation pressures gives the least value, and tests by the constant volume method give intermediate values. However there is no definite relationship between the three methods. The paper also shows that time effects involved in conducting the tests and the effect of stress path are both significant. Time versus swelling, and to a greater extent, time versus pressure relations can be represented by a rectangular hyperbola, which can be used to predict the ultimate swelling and the swelling pressure, respectively. Tests with varying initial conditions of molding moisture content and density have exhibited a unique relationship between swelling pressure and the initial dry density for black cotton soil. This result is in line with the osmotic pressure theory. The molding water content has marginal effect on the swelling pressure.

Ground granulated blast furnace slag amended fly ash as an expansive soil stabilizer

The standard and modified Proctor compaction tests are devised to establish dry unit weight-water content relationships for a soil under controlled conditions, such as compactive effort, water content, etc. This paper presents a mini compaction apparatus primarily for use in fine grained soils, which requires only about 1/10th volume of soil needed for the standard and modified Proctor test. Additionally, the time and effort involved in carrying out the compaction test is much less. Also, the compacted soil sample, after trimming, can be used for strength tests.
