| Summary |
"This study was undertaken to investigate the effect of varying amounts of clay (illite) on the compressibility of a silt as it may be found in nature in a normally consolidated deposition. Laboratory procedure was designed to minimize sample disturbance so as to obtain, as nearly as possible, a virgin consolidation curve. By varying the amounts of silt and clay in a given sample, and sedimenting the sample from a soil-water suspension, consolidation test analyses were used for a comparison of the various samples. Results revealed that between sample mixtures of 40 and 60 percent silt there was a relatively large change in the proportionality of compression index to liquid limit, and that the compression index varied directly with the percent silt present in the sample. A method of predicting settlement characteristics from existing water content, overburden pressure and percent silt was also suggested. Furthermore, it was evident that small changes in silt content had a considerable effect on the consolidation time of silt-clay mixtures"--Synopsis, leaf 1. |
