The creep behaviors of silicate-grouted sandy soil were investigated. A series of haversine creep tests with three frequencies (0.01 Hz, 0.05 Hz, and 0.1 Hz) were carried out to evaluate the dynamic properties (complex modulus and phase angle) of materials at low stress level. The stress-strain relationship for the sinusoidal test was plotted as an elliptical hysteretic loop. The complex modulus |G*(ω)| and the phase angle δ were determined from the hysteretic loop at a given frequency ω. While the complex modulus |G*(ω)| of the tested material increased, the complex compliance |J*(ω)| and the phase angle δ decreased with frequency ω within the tested frequency range.
