This paper presents the using of shear wave velocity to determine the cementation effect of soft Bangkok clay mixed with cement and fly ash. The Bangkok clay is mixed with 20 % of the Portland cement type 1 by weight of dry soil and varied the replacement of fly ash 10, 15, 20, 25 and 30 % by weight of cement. Then, these samples were cured to 7, 14, 28 and 90 days respectively and performed the bender element and unconfined compression test. From the results, the research found that the undrained shear strength and the shear wave velocity increased with increasing the curing time. The undrained shear strength data of 15 % of fly ash type F were maximum values and in good agreement with the result of no fly ash. In the similar ways, the shear wave velocity results of 15-20 % of fly ash type F were higher than the result of no fly ash in the long term. The relationship between the shear wave velocity and the undrained shear strength was Vs = 243.38(Su/Pa)0.305 and in good agreement with the field data.
