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 ...
Polymer soil stabilization refers to the addition of polymers to improve the physical properties of soils, most often for geotechnical engineering, construction, or agricultural projects. [1] Even at very small concentrations within soils, various polymers have been shown to increase water retention and reduce erosion, increase soil shear ...
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.
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 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.
A 1,300,000-square-foot (120,000 m 2) complex of mixed residential, office, retail and commercial space is being built on 15 acres (61,000 m 2) of former industrial land in downtown Victoria that was contaminated by lead. 10 tonnes of soil was treated with cement, which was mixed into the soil on site simply by using an excavator bucket. The ...
Early research (Bathurst and Jarrett, 1988) [13] found that cellular confinement reinforced gravel bases are "equivalent to about twice the thickness of unreinforced gravel bases" and that geocells performed better than single sheet reinforcement schemes (geotextiles and geogrids) and were more effective in reducing lateral spreading of infill under loading than conventional reinforced bases.
Soil cement, a mix of pulverized natural soil with small amount of Portland cement and water; Cellular confinement, a honeycomb-like plastic soil stabilizer; Soil stabilization, a way of improving the weight bearing capabilities of sub-soils, sands, and other waste materials; Soil stabilizer (vehicle), a machine used to make soil cement
