INFLUENCE OF LIME ON THE SECONDARY COMPRESSION CHARACTERISTICS OF BANDUNG CLAY, Helms, Achmad, 1987, Program Sistem dan Teknik Jalan Raya, Fakultas Pasca Sarjana, Institut Teknologi Bandung. The interaction of lime on the general consolidation characteristics of Bandung clay has been examined in a previous study, which included tests on a wide range of lime contents either inserted totally mixed with the clay or in column form. That study suggested that lime had an influence on reducing the general settlement characteristics of Bandung clay, particularly at the higher range of lime contents applied. That study also confirmed that the secondary compression component of the settlement of the natural soil was significant. The research discussed in this thesis was primarily concerned with examining in some detail the secondary compression characteristics of Bandung clay, both in the natural state and when treated with lime, either in a totally mixed state or using a lime column with percentages of lime, based on dry weight of soil, of 10% and 15X. A few tests were also carried out using taller soil specimens (60 mm) compared with the conventional oedometer specimen height of 20 mm. The addition of lime as an agent to strengthen Bandung clay resulted in increases in strength as time increased. The introduction of lime was found to effect a significant reduction on secondary compression for both the standard 20 mm and taller 60 mm cell. The influence of lime on settlement performance at high and low effective consolidation pressures were very significant. The introduction of lime was found to increase the value of pH, in line with the reduction of secondary settlement observed.
