  3. Abstract:
  4. In this paper dynamic property of Cement-Admixed clay under a wide range of strains were studied considering the effect of different mixing ratio and the change of confining pressures through dynamic triaxial test. Triaxial tests were conducted on untreated and cement treated soils and the results were then analyzed to study the variations in dynamic elastic modulus (Ed) and the damping ratio (D) of soil specimens at different cement ratio. Increasing cement ratio has a significant effect on Ed of the treated soils, and increases it. In contrast, increasing cement ratio decreases D; however, the rate of decreasing D with increasing cement ratio is not considerable. The feed-forward Artificial neural network (ANN) was used to estimate the dynamic elastic modulus and damping ratio of The Cement-Admixed clay used in the tests. Strain level, confining pressure and cement ratio in the mixture were used as inputs of ANN and the outputs were Ed and D. The neural network model can accurately represent the effects of confining pressure, cement ratio and strain level on dynamic properties of the composite cemented clay
