it becomes less effective due to low increment in strength. Therefore salt is used to accelerate lime-organic soil reactions. Salt is introduced to remove the barrier in order to accelerate as well as help lime to increase the strength of organic soil. Hydrated lime & salt of Sodium (NaCl) is used here for the stabilization of organic soil.   Lime is the oldest traditional stabilizer used for soil stabilization. The mechanism of soil-lime treatment involves cation exchange, which leads to the flocculation and agglomeration of soil. SOIL STABILIZATION WITH CEMENT AND LIME. This book reviews the subject of soil stabilization which is the process whereby soils and related materials are made stronger and more durable by mixing with a stabilizing agent. The process enables materials to be employed in the construction of road pavements which without stabilization would be Cited by: prolonged soaking. Lime stabilization occurs over a longer time period of “curing.” The effects of lime stabilization are typically measured after 28 days or longer, but can be accelerated by increasing the soil temperature during the curing period. A soil that is lime stabilized also experiences the effects of soil drying and modifi cation.

A number of researchers have studied the stabilization of soft soil by cement [7][8][9][10]; cement-ground granulated blast furnace slag [2,11] and lime-cement [12]. examined swell caused by lime stabilization of sulfate-rich soils. Mitchell and Dermatas systematically added sulfates ranging from to 62, ppm to artificial kaolinite- and montmorillonite-rich soils.6 This study focused on extremely high sulfate concentrations and extended curing times, generally 30 . Lime can stabilize fine-grained subgrade or subbase. Subgrade stabilization usually involves in situ mixing of soil and stabilizer, and generally requires 3 to 6 per cent of lime by weight of the dry soil. If quicklime is used as a form of lime in soil stabilization, it . TxDOT) for stabilization with traditional calcium-based stabilizers like lime and cement. More specifically, soils with sulfate concentrations ab ppm were stabilized with numerous nonstandard stabilizers and evaluated with respect to 3-D swell and.

effects of cement and lime in the deep stabilization of different soils [5]. The project yielded results that should permit the stabilization of organic soils such as mud and peat. At the same time, mass stabilization has been introduced in Sweden. Mass stabilization is a new technique for the stabilization of loose soil layers such as peat and. and physical stabilization, for example, by using lime and geofiber or geotextile together (Yang et al., ; Chong and Kassim, ). Lime is the oldest traditional chemical stabilizer used for soil stabilization (Mallela et al., ). However, soil stabilization using lime involves advantages and disadvantages. This study provides. Calcareous soils containing organic matter appear to respond better to lime stabilization than acid soils. This study was the first to provide direct evidence of the effects of organic matter on soil stabilization. Key Words Humic Acid, Lime Stabilization, Organic Soils, UV-Vis Method, Organic Matter Measurement Distribution Statement. The principle uses of the additions of lime to clay soils is for, firstly, stabilisation of subbases and subgrades in pavement construction and, secondly, to dry out wet soils. Lime treatment also has been used to stabilise embankments and canal linings, and to improve foundation soils.
