Lime and/or cement stabilisation is often used to improve the properties of site won materials, to enable their use in a pavement and other like areas, such as dam foundations and building pad sites. Lime stabilisation of clay material reduces entrance cracking, whilst increasing the hardness of the material by up to ten times. The …
of the expansive minerals. Using a low aluminate Portland cement (such as type V, sulfate-resistant cement) does not solve the problem because the source of the aluminum is not entirely the Portland cement but the soil. There is no easy answer to the problem. Calcium is present when either lime or Portland cement are used for soil stabilization.
The findings demonstrate that either cement or lime may be applied to improve the properties of sabkha soil. CBR and UCS tests are the most effective …

Introduction The Stabil-Lime Group is a specialist lime and cement soil stabilisation company. Their scope of work also includes construction and the supply and distribution of binders used in the soil stabilisation process. Soil stabilisation, in terms of pavement construction, is the process of (usually insitu) pulverising and moisture conditioning by …
Lime stabilization remains the most commonly adopted method to improve expansive soil; however, lime production has drawbacks such as depleting natural …
Soils can be stabilized by the addition of cement or lime. Such stabilization processes improve the various engineering properties of the stabilized soil and generate …
Cement stabilization develops from the cementitious links between the calcium silicate and aluminate hydration products ... cement, combinations of lime and cement, Sarooj (artificial pozzolan) and heat treatment were utilized. Lime and cement were supplied by Oman Cement Company. Sarooj was produced in the Civil …
A plethora of stabilization techniques are available and they may be grouped into physical, chemical, mechanical stabilization [Citation 7–12] and biological …
Lime and cement both enhanced the strength of sabkha soil when the moisture content was normal, but cement was the only chemical that successfully stabilized sabkha soil when the moisture content was high. ...

Such a chemical means of stabilization using a manufactured product is only effective if it is added to the appropriate soil type and soil layer in the right amounts. Chemical agents for this purpose include fly ash, lime-cement, lime, Portland cement, or bitumen; these can be added individually or mixed with other agents (Olarewaju et al. …
Learn how lime or cement stabilization can enhance soil properties for engineering projects, but also cause environmental and social impacts. Explore alternatives and tips for soil improvement.
Subcommittee on Lime Stabilization and published in 1959 as ARBA Technical Bulletin 243. The National Lime Association assumed publication rights in 1965. ... (make it workable) for further stabilization with Portland cement or asphalt. Generally, between 1 and 4 percent lime will dry a wet site sufficiently to allow construction activities to ...
Performance of the pavement is largely attributed to the quality of the sub-base and subgrade layer. In country like India, nearly, 0.8 million square km of the total area covers expansive soils which are also known as black cotton (BC) soil. The shrinkage and swelling characteristics of the BC soils are biggest challenge to any highway …
In this study, Al-Khod (town in northern Oman) expansive soil was stabilized using lime, cement, combinations of lime and cement, Sarooj (artificial pozzolan) and heat treatment.
The chemical reactions that occur during soil stabilization using FA resemble the reactions that occur during soil stabilization using cement/lime. Initially, the monovalent cations are replaced with Ca 2+ to reduce plasticity (Christopher et al. 2000). Cementitious and pozzolanic reactions during soil stabilization with FA can be …
Methods of Soil Stabilization for Pavements 1. Cement Stabilization of Soil for Pavements Those factors which are most important for a quality control standpoint in cement stabilization are: pulverization, cement content, moisture content, uniformity of mixing, time sequence of operations, compaction, and curing. These are described in …
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 ...
The results showed substantial improvements in maximum dry density, unconfined compressive strength, and shear strength parameters (c and φ). Thus …

Stabilisation of clayey material with lime generally results in pavements that have a much lower cracking potential than if the subgrade has been cement stabilised. Lime stabilised subgrades are also more durable as the effect of the clay has been reduced, rather than masked, as is the case with cement stabilisation.
