Stabilization using solid wastes is one of the methods of treatment, to improve the engineering properties and make it suitable for construction. This paper presents a review of literature on stabilization of expansive soil using solid wastes.
waste material can use in stabilization of soil..ex. flyash used as stabilizer to improve the geotechnical characteristics of soils..your question is not very clear..
Waste materials can be used to improve soil properties. Some waste materials can be used to replace a portion of lime used for soil stabilization to make the process cost effective and eco friendly where by disposal of waste issues can be solved. Fly ash, rice husk ash, egg shell powder etc have been successively used in soil stabilisation. Cement waste etc may be ground to powder form and mixed with soil to significantly improve soil properties
waste materials used for soil stabilization. It means improvement in poor/soft/expansive soil properties like LL, PL, CBR, USC, Swelling, Swelling Pressure etc. There are various waste materials like fly ash, glass fibers, tyre pieces, rise husk, coir fiber etc.
In addition to the above submissions, the application of Solid waste in Soil Stabilization is taking new procedures and techniques. But also remember that the waste products of renewable energy conversion cycle; fly ash, granulated slag, charcoal, etc are all in use as binders, Cementitous materials and additives in the stabilization of expansive Soils. There is also an ongoing research to determine the durability of Solid waste ash stabilized soils. Stabilized soils are hydraulically bound materials and there is need to examine the durability of these stabilized matrixes using the loss of strength on immersion method. Results of this work would be published soon.
Stabilization using solid wastes is one of the methods of treatment, to improve the engineering properties and make it suitable for construction. This paper presents a review of literature on stabilization of expansive soil using solid wastes.
Three issues on the reuse of materials in geotechnical applications in Japan are presented in this paper. First, current status of reuse of excavated soils is presented. Since natural contamination has been a concern these years, several efforts including experimental studies to evaluate the environmental suitability of these materials have been conducted. Second, traceability in environmental geotechnics has been becoming an important consideration. One joint project, in which the excavated soils generated from shield tunnel excavation are utilized as a soil material for reclamation, utilizes the electronic toll collection (ETC) system to track the soil materials. Third, utilization of disaster wastes caused by the 2011 East Japan earthquake and tsunami is required. Challenges include the proper treatment to separate soils from waste mixture and to utilize these soils in geotechnical applications.
The use of waste in the field of soil stabilization is considered a highly scientific matter, taking into consideration the specifications of these wastes, and not to damage the soil. One example is the application of cement dust, dry plant fiber in doing so.
This relationship should studied well and more detailed information is needed. Sometimes waste can improve the soil parameters and sometimes make it worth.
One should specify and study each case well before applying it.
The general idea at the back of such studies is the knowledge improvement on the possible conversion of a problematic waste product into a valuable industrial or construction material.
Recently, global extensive efforts are underway in order to recycle and use of waste tires in form of tire derived aggregate (TDA) for different civil engineering purposes via production of both construction materials and geomaterials.
In geotechnical applications, these shredded and granulated forms of scrap tires are mixed with sand and/or silt to form what are commonly referred to as tire derived aggregate (TDA) soil mixtures.
The employment of such mixtures as lightweight fill material for embankments and bridge abutments as well as their uses for backfilling retaining walls are well documented.
For more information on TDA, its unique properties and its applications as geomaterial I invite you to follow the link below in order to access to a full-text version of the newest publication (Jan 2020) on modeling of TDA long-term deformation (Creep).

Chemical remediation fly ash, blast furnace slag, marble dust are usually provided by materials such as lime, cement, asphalt, or wastes. We can count the wastes used for chemical remediation. If large pieces of the desired aggregate break while using, the mix of dust wastes the soil is expected which enters the reaction.
