Amelioration of soil structure leading to a reduction of mineralization by means of protecting soil organic carbon. Liming is known to ameliorate soil structure, as high Ca 2+ concentrations and high ionic strength in the soil solution enhance the flocculation of clay minerals and, in turn, form more stable soil aggregates. [9]
Yet another solution is a process called soil stabilization, in which additional materials are added to the soil to limit its ability to shrink and swell. [7] Materials for stabilization include cement, resins, fly ash, lime, pozzolana, or lime-pozzolana mixture, [7] depending on the site conditions and the project goals.
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils , sands, and waste materials in order to ...
Soil sieve nests with dry soil aggregates after removal from a laboratory drying oven. Soil aggregate stability is a measure of the ability of soil aggregates—soil particles that bind together—to resist breaking apart when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes, and tillage.
Mixtures of cement and lime, or pozzolana and lime, may also be used for stabilization. [19] Preferably the sand content of the soil will be 65% – 75%. Soils with low clay content, or with no more than 15% non-expansive clay, are suitable for stabilized earth. [20] The clay percentage may be reduced by adding sand, if available. [21]
If the soil particles in a sample are predominantly in a relatively narrow range of sizes, the sample is uniformly graded. If a soil sample has distinct gaps in the gradation curve, e.g., a mixture of gravel and fine sand, with no coarse sand, the sample may be gap graded. Uniformly graded and gap graded soils are both considered to be poorly ...

Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...
