Comparative Study of Soil Stabilization Using Human Hair and Lime Abstract— recent issues regarding solid waste disposal demands novel methods for their proper utilization. Lime has been mainly used for stabilizing the road bases and the subgrade. If clay contains gravel in it, then lime acts as binding material for clayey gravel. Soil pH, organic content, the quantity of exchangeable sodium, clay mineralogy, natural drainage, weathering conditions, extractable iron, carbonates and silica-alumina ratio are some of the properties which influence the gain in strength. By using lime, soils can be stabilized, dried and modified. Determining the amount of lime necessary is part of the design process and is approximated by tests … The methods are: 1. We understand that the amount of lime that soil requires for stabilization varies between 2 to 10 percent of the soil. Method # 1. The … SOIL STABILIZATION USING LIME AND CEMENT 1. Lime Stabilization ... in the soil system, which in turn reduces the strength. Figure 3: Lime-stabilized layer (see arrow) bridging an erosion failure illustrates strength Lime, either alone or in combination with other materials, can be used to treat a range of soil types. Among chemical types of soil stabilization lime application is also very common. Stabilization differs from modification in that a significant increase in strength is developed over the longer term through an on-going pozzolanic reaction. This new technique of soil stabilization can be effectively used to meet the challenges of society, to reduce the quantities … Introduction Soil Improvement • To increase bearing capacity and stability (avoid failure ) • To reduce post construction … The sulphate in the soil is known to be able to cause serious swelling in stabilized clay. which can be done by use of controlled compaction or addition of suitable admixtures like cement, lime and waste materials like fly ash, phosphor gypsum etc. Complex Stabilization. Cement Lime Stabilization 11. The principle involved in lime-soil stabilization is the exchange of ions between lime and soil when added.When clayey soil is treated with lime, Cation exchange takes place between them which increases plastic limit and reduces plasticity index which finally results in increase in stability of soil. Soil stabilization is a process which improves the physical properties of soil, such as increasing shear strength, bearing capacity etc. This is useful for the stabilization of clayey soil. Environmental problems associated with Human hair fiber, a non- degradable matter can be minimized by using the same as a reinforcing agent in soil stabilization. Soil stabilization a general term for any physical, ... Cement fly ash, lime fly ash (separately, or with cement or lime), bitumen, tar, cement kiln dust (CKD), tree resin and ionic stabilizers are all commonly used stabilizing agents. Electrical Stabilization 7.
Use of lime significantly changes the characteristics of a soil to produce long-term permanent strength and stability, particularly with respect to the action of water and frost. Lime stabilization improves the strength, stiffness, and durability of fine-grained materials. Author(s) CEEn 563 Pavement Design. This project aims to conduct a study to carry out the above-mentioned process using polypropylene fiber which is basically a textile consisting of a network of natural or … When lime reacts with soil there is exchange of cations in the adsorbed water layer and a decrease in the plasticity of the soil occurs. USING LIME FOR SOIL STABILIZATION AND MODIFICATION A PROVEN SOLUTION! Download Study . Soil Lime Stabilization 2. Sandy soils can also be stabilized with these combinations. Soil-Bituminous Stabilization 4. According to [6], a combination of lime and granulated blast furnace slag is commonly used in South Africa and Australia for soil stabilization. The advantage of using lime as a soil stabilizer is basically concerned with many reasons such as reduced construction or operational cost during process of the project especically, reduce water use energy consumption and a reduction of Co2 emissions as well as saving time of operational processes.
