  2. Soil stabilization - Wikipedia

    en.wikipedia.org/wiki/Soil_stabilization

    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 ...

  3. Mechanically stabilized earth - Wikipedia

    en.wikipedia.org/wiki/Mechanically_stabilized_earth

    Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls , bridge abutments, seawalls , and dikes . [ 1 ] [ 2 ] Although the basic principles of MSE have been used throughout history, MSE was developed in its current form in the 1960s.

  4. Earth structure - Wikipedia

    en.wikipedia.org/wiki/Earth_structure

    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]

  5. Soil conditioner - Wikipedia

    en.wikipedia.org/wiki/Soil_conditioner

    In general usage, the term "soil conditioner" is often thought of as a subset of the category soil amendments (or soil improvement, soil condition), which more often is understood to include a wide range of fertilizers and non-organic materials. [1] In the context of construction soil conditioning is also called soil stabilization.

  6. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    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 ...

  7. Shrink–swell capacity - Wikipedia

    en.wikipedia.org/wiki/Shrink–swell_capacity

    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.

  8. Soil aggregate stability - Wikipedia

    en.wikipedia.org/wiki/Soil_Aggregate_Stability

    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.

  9. Environmental remediation - Wikipedia

    en.wikipedia.org/wiki/Environmental_remediation

    Stabilization involves the addition of reagents to a contaminated material (e.g. soil or sludge) to produce more chemically stable constituents; and Solidification involves the addition of reagents to a contaminated material to impart physical/dimensional stability to contain contaminants in a solid product and reduce access by external agents ...
