In this study, stress relaxation tests were carried out by keeping cement stabilized sand (CSS) specimens with different particle size distributions and cement contents under various strain levels. Time-dependent decreases in the stress values were collected to better understand the effect of the strain level on the relaxation properties of the cement stabilized sand specimens. In addition, the stress relaxation effect on the uniaxial compressive strength (UCS) values of the CSS specimens was investigated with a series of tests. According to the results obtained from this study, UCS values of the CSS specimens vary depending on the strain level during the stress relaxation. The UCS values were determined to significantly decrease in case of high-stress levels at the initiation of the relaxation, which are close to the peak value. The stress relaxation rate was measured to be rapid in the first minutes and remarkably decrease with an increase in the duration of the relaxation. Cement content was found beneficial to improve the relaxation resistivity of the CSS samples. As another outcome of this study, the fines particle content was determined to cause decreases in the strength values after the stress relaxation effect. [ABSTRACT FROM AUTHOR] |
