“…However, in the grey soil there is a considerable increase in the internal friction angle beyond 28 days. A similar trend was found by Sezer et al [41] where they used a very high lime-fly ash content and concluded that this behavior is probably due to the fact that the internal friction angle of the fly ash is more greater than that of the soil.…”

“…4b, c, d), which is consistent with the general behavior of cement-treated clays [55,70,78] In general, an increase in / d induces higher shear strength and bearing capacity at greater depths, while the increase in c d becomes meaningful for subsurface soil strengthening. Thus, it can be concluded that gellan gum treatment can be effective for improving the shear strength of shallow subsurface sand layers, such as seashore or arid region dunes, by increasing c d (Fig.…”

Shear strength behavior and parameters of microbial gellan gum-treated soils: from sand to clay

Microbial biopolymers have recently been introduced as a new material for soil treatment and improvement. Biopolymers provide significant strengthening to soil, even in small quantities (i.e., at 1/10th or less of the required amount of conventional binders, such as cement). In particular, thermo-gelating biopolymers, including agar gum, gellan gum, and xanthan gum, are known to strengthen soils noticeably, even under water-saturated conditions. However, an explicitly detailed examination of the microscopic interactions and strengthening characteristics between gellan gum and soil particles has not yet been performed. In this study, a series of laboratory experiments were performed to evaluate the effect of soil-gellan gum interactions on the strengthening behavior of gellan gum-treated soil mixtures (from sand to clay). The experimental results showed that the strengths of sand-clay mixtures were effectively increased by gellan gum treatment over those of pure sand or clay. The strengthening behavior is attributed to the conglomeration of fine particles as well as to the interconnection of fine and coarse particles, by gellan gum. Gellan gum treatment significantly improved not only interparticle cohesion but also the friction angle of clay-containing soils.

“…The unreacted lime that is not combined in any of these compounds is called free-lime, which is expected to play a major role in stabilization (Collins and Emery, 1983;Misra, 1998;Zaman et al, 1998;Ferguson and Levorson, 1999;Miller and Azad, 2000;Miller and Zaman, 2000;Sezer et al, 2006;Khoury and Zaman, 2007;. Free-lime content was determined by conducting titration in accordance with ASTM C 114 alternative test method B and results are presented in Table 1.…”
