Laboratory Strength Correlations for Cement-Treated Peat

This paper develops a correlation of the unconfined compressive strength of treated peat-cement samples. The strength is directly evaluated from mechanically-mixed specimens and laboratory-scale auger columns. The results obtained show both the effect of the cement quantity and the effect of two specimen sizes on strength. Generally, the higher the quantity of cement added to the peat, the higher the strength gained. Furthermore, a comparison between results in this study show that the strength obtained from mechanically-mixed specimens is twice as large as that obtained from laboratory-scale auger columns. Therefore, the conclusion is that the parameters obtained from laboratory-scale auger columns can be closer to those measured at the field than those obtained from mechanically-mixed samples.
