"The effect of temperature, organic carbon content, and preloading on secondary consolidation of Bryce clay has been studied. A straight line plot of void ratio versus logarithm of time was established in secondary consolidation for long term loading periods up to one month. Temperature changes within the range of 5ºC. to 45ºC. were studied in the secondary consolidation phase at different stress levels and different carbon contents of the soil. Secondary consolidation in a preloading cycle at a stress level of 2 tsf unloaded to 1 tsf and reloaded to 2 tsf was studied. The preloading tests were at temperatures of 5ºC., 25ºC., and 45ºC. on samples of varying carbon contents. It was found that the value of Cα (secondary consolidation rate expressed as the void ratio per cycle of logarithm of time) could be reduced by preloading at a constant temperature. At higher effective stresses, Cα was found to be dependent on the carbon content of the soil at 25ºC. and 45ºC., and under the same conditions, Cα was independent of the carbon content at 5ºC. At a given temperature a value of Cα was established. If the temperature was increased for a period of time and then lowered to the original temperature, the final en was considerably less than the original Cα. If the temperature was decreased between a given initial and final temperature, it was found that Cα was only slightly affected"--Abstract, pages ii-iii.
