Thus, according to the results of soil improvement, the strength of soil-cement mixture containing 3% Portland cement is approximately equal to that of soil-lime containing 10% lime. Both the,Improving Soil With Gypsum - Garden.org,Gypsum as Soil Conditioner. Gypsum can reclaim high-sodium or "sodic" soils. Soils with a high proportion of exchangeable sodium (Na+) lose structure. Once soil is tightly packed, water and air penetration is reduced and root growth suffers. Water often puddles on the surface of these soils. To revitalize sodic soils, incorporate gypsum into the soil and then apply six or more inches of water,Ground improvement using soil–cement columns:,01/12/2013· Depending on both the replacement area ratio and the column length, the soil improvement using the soil–cement columns could reduce up to 80% of the maximum settlement of unimproved soil. 10. The Bearing capacity of soil improved by soil–cement columns after 28 days of curing was higher by 3–16% than the bearing capacity of improved soil after 7 days of curing.

Review on the effect of gypsum content on soil behavior,

01/09/2015· Artificially added gypsum, when gypsum and/or bassanite (virgin or recycled) are added to non-gypsiferous subgrade soil in control quantities to improve the mechanical properties of the subgrade soil (due to the cementation action of gypsum) and/or to minimize the landfilling of waste products involve gypsum, since the use of secondary (recycled) instead of primary (virgin) materials in roads,Gypsum - an overview | ScienceDirect Topics,Furthermore, gypsum is used for soil improvement in the form of fertilizer and soil conditioner. Gypsum is often used as part of a strategy to correct compacted soil or soil with large amounts of clay. It is also used to counteract excessive saline levels in soil and has the added benefit of not affecting the pH of soil.
