GT-89-16 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 1990 Laboratory tests on lime- flyash and cement-flyash treated clay were carried out to study the strength and deformation characteristics. The materials used were Ordinary Portland Cement 'Tiger Brand', Hydrated Lime, Fly ash from 'EGAT' and the soft Bangkok clay taken from AIT campus. Two types of strength tests, i.e. unconfined compression and Iso tropically Consolidated undrained triaxial compression tests were performed. Consolidation tests were carried out to study the compressibility data for settlement analysis. The UC test results showed that the effect of lime- fly ash stabilization was 3 times that of untreated clay, where as cement-fly ash stabilization showed .a strength gain more than 7 times in 2 months curing time (17 . 31 t/m2 for 2~% fly ash + 5% cement ) The oedometer consolidation test results showed an improvement in the consolidation characteristics of the clay effectively by an increase in the Cv values and a decrease in the Cc. The apparent pre-consolidation pressure increas~d to 30 t/m2 ( 0% Aw + 25% FA } when compared to LAW (1989) where Ovm = 15 t/m2 ( 5% Aw only} . CIU triaxial compression test data revealed that the main effect of the lime-fly ash and cement-fly ash treatment on soft Bangkok clay was to change the strength and deformation characteristics of the soft-clay from NCC to OC clay behaviour. There are indications that factors affecting lime-fly ash and cement stabilization are similar in modifying the pbysio-chemical characteristics of clayey soil. The results of the study were compared with the previous studies carried out on lime YANG (1 988 ) and cement stabilization LAW 1989, and it was observed that the change of the stabilizer (i.e. presence of fly ash} had a pozzolanic effect in the cementation processes involved, resulting in a complete change in the effective strength parameters. The angle of sharing resistance {u00A2} decreased from 36.6° LAW (1989) to a value of 11.21° by the addition of fly ash in present study, but the cohesion intercept c has been found to increase significantly with cement-fly ash to a maximum value of 8.15 t/m2 when compared to LAW (1 989 }, where C= 2.57 t/m2 (7.5 cement content only) .
