Sc.) - Asian Institute of Technology, 1997  aThe strength and deformation characteristics and the time dependent behaviour of the  cement treated Bangkok clay were studied through comprehensive series of unconfined  compression and oedometer tests. The base clay used were lightly overconsolidated soft  Bangkok clay, at a depth of 3 to 4 m from AIT campus. Type I Portland cement powder was  used to stabilize the soft clay and cement content of 150 and 200 kg/m3  were used. Both dry  and slurry mixing were used for Unconfined Compression Test and Oedometer Tests. For  Unconfined Compression Tests, curing period of 3, 7, 14, 28, 60, 90 and 120 days, w/c ratio  of 0.5, 0.6, 0.8, 1.0, 1.2 were used. For oedometer tests, curing period of 7, 28, 60 and 90 days  with w/c ratio of 1.0 were used.  The unconfined compressive strength of cement treated sam~les were found to increase  with curing time. For dry mixing, cement content of 150 kg/m could be regarded as an  optimum cement content for long term curing period. Strength increment of sluny mixed  samples reduce with increase in w/c ratio. Oedometer tests revealed that the cement treatment  caused substantial improvement of consolidation properties, apparent preconsolidation  pressure, reduction of compression index (Cc), increase the value of coefficient of  consolidation (Cv)·. Coefficient of permeability of cement treated soil is smaller than the  untreated soil, and hence it is not suitable as material for vertical drain.  As compared with previous research from AIT, laborato1y studies on the use of various  additive to soft Bangkok clay indicated that cement is the most superior additive in achieving  higher strength within the optimum specific time of curing.The improved strength of treated  samples are dependent on strength and physical prope1ties of untreated clay, mixing method,  sample preparation, sample curing method, curing time, w/c ratio and cement content.  Unconfined compressive strength of treated samples from the same location can differ a lot  depending on sample preparation and curing method 10aSoil stabilizationxThailandxBangkok0 aNoppadol Phien-Wej,eChairperson1 aBergado, Dennes T.,eExamination Committee1 aKohgo, Yuji,eExamination committee2 aAsian Institute of Technology Partial Scholarship,eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
