A serious disadvantage of the acid stabilization of clay soils is the technical difficulties associated with the need to mix acid with the soil and the impossibility of its injection into practically impermeable soils. This is an obstacle to the use of acid stabilization in foundation building....
Chemical soil stabilization has been widely practiced in many European countries and numerous states in the US. The process involves the incorporation of hydraulic binders: namely, lime and cement, which in turn enhance the physical properties of the host soil. Soils best suited to the process typ...
This study investigated the effects of surface functional groups, cation exchange capacity (CEC), surface charge, sesquioxides and specific surface area (SSA) of three soil clay fractions (SCFs) (kaolinite–illite, smectite and allophane) on the retention of dissolved organic carbon (DOC) in soi...
With the addition of more lime, the particles previously aggregated react further to form particles of a size larger than 0.075 mm. Some preliminary work on the chemistry of lime stabilization of black cotton soil indicates that the aggregation of clay particles with calcium hydroxide is very ...
Besides liquid transport many other processes contributing to soil functioning such as adsorption and stabilization of OM and pollutants as well as biological interactions rather are controlled by BGI wetting properties than by bulk particle or bulk soil characteristics. The CA is determined by polarity...
CEC = cation exchange capacity (1 N NH4OAC pH = 7), where P is available phosphorus assessed using the Bray II method; pH = soil pH (1:1 H2O); clay and silt are percentages of clay and silt content; and DOC/P is the ratio of DOC to P. 3.4. The Interrelation between Soil ...
Ekinci (2019) explored the strength and microstructural properties of marine clay-cemented mixes [27]. Rashid et al. (2017) employed the field emission scanning electron microscopy to inspect the effectiveness of xanthan gum for the stabilization of tropical laterite soil [28]. However, in most ...
In addition, clay–lime stabilization/solidification followed by Portland-cement stabilization/solidification could be efficient in immobilizing the recalcitrant and hazardous constituents of the contaminated soil. They concluded that these two-step stabilization/solidification processes can be necessary to ...
This process promotes the formation and stabilization of clay clusters16,32. Our results suggest that the incorporation of VC as organic amendment increases the effectiveness of GP and ES improving soil physical health in saline-sodic soils. The CDR (Table 2) was significantly correlated with the ...
