In this study, the specification of silty soils with fly ash and effect of curing time in mixture of silty soil with C type of fly ash has been researched. In this paper tests such as dertermination of water content, Atterberg limits, Standard proctor and Unconsolidated Undrained Triaxial (UU) tests has been done. By adding different amount of fly ash (3%, 5%,7% and 10% ) and curing time of (1, 7, 14) days, the internal angle of friction and shear strength has been increased. The maximum increase occurred by adding 3% fly ash in 7 days. Atterberg limits on different combination of soil- fly ash show almost same results and do not have noticeable changes.
