The present disclosure relates to soil stabilizing compositions and particularly relates to a method for stabilizing soil.
Soil stabilization may be a general term for any physical and chemical method of changing a natural soil to a soil with specific properties. For example, a soil stabilization process may be used to enhance shear strength and adjust the shrink-swell properties of a soil sample. A stabilized soil may be necessary for industrial processes and constructions.
One approach for soil stabilization is to add a stabilizing agent to the soil. Various materials may be used as stabilizing agents, such as synthetic and natural materials. Stabilizing agents may include cement, bitumen, calcium hydroxide, sodium chloride, calcium chloride, sodium silicate, geotextiles, and plants. However, synthetic stabilizing agents may be expensive and have a non-biodegradable nature.
On the other hand, natural stabilizing agents are renewable, low cost, and eco-friendly resources that may be used in soil stabilization. However, soil treatment by calcium-based additives may have a number of inherent disadvantages, such as carbonation, reduction of the pH value, sulfate attack, and environmental impact. Furthermore, using bitumen as a soil stabilizer may reduce shear strength and may tend to become brittle over time.
There is, therefore, a need for an eco-friendly and low cost soil stabilizing compound. There is further a need for developing a method for producing a soil stabilizing compound with high specific surface area for interaction with soil particles.
