Adsorbed Moisture

Problematic soil stabilization processes involve the application of binders to improve the engineering properties of the soil. This is done to change the undesirable properties of these soils to meet basic design standards. However, very little attention has been given to the reactive phase of soil stabilization. This phase is the most important in every stabilization protocol because it embodies the reactions that lead to the bonding of the dispersed particles of clayey soil. Hence, this reactive phase is reviewed. When clayey soils which make up the greatest fraction of expansive soil come in contact with moisture, they experience volume changes due to adsorbed moisture that forms films of double diffused layer on the particles. When this happens, the clayey particles disperse and float, increasing the pore spaces or voids that exist in the soil mass. Stabilizations of these soils are conducted to close the gaps between the dispersed clayey soil particles. This is achieved by mixing additives that will release calcium, aluminum, silicon, etc., in the presence of adsorbed moisture, and a hydration reaction occurs. This is followed by the displacement reaction based on the metallic order in the electrochemical series. This causes a calcination reaction, a process whereby calcium displaces the hydrogen ions of the dipole adsorbed moisture and displaces the sodium ion responsible for the swelling potential of clayey soils. These whole processes lead to a pozzolanic reaction, which finally forms calcium alumina-silica hydrate. This formation is responsible for soil stabilization.

Standard Techniques

Clayey soil is one of the problematical soil around the world which causes distress to the construction that is built over clayey soil. Construction on expansive soil for geotechnical application causes major problems due to its poor shear strength characteristics apart from this continuous variation in volume change. soil stabilization is the process for modifying the engineering properties of soil. It is one of the most standard techniques used for the improvement of poor soil and also to make cost-effective way by making the best use of the locally existing material. For quite a while, cement is the well-known binder in soil stabilization, but it emits a large amount of CO2 , and energy depletion has started using some other materials or by-products to exchange cement for soil stabilization in full or in part. The growing volume of greenhouse gasses such as CO2 has also started explore into finding soil stabilization ecologically friendly resources. Dunite’s have a high amount of MgO, Al2O3 , SiO2 , and Fe2O3 could categorize this mineral as a soil stabilizing pozzolanic material. In present work experiment were conducted by addition of clayey soil with various percentage of Dunite powder (5%,10%,15%,20%) is added with the dry weight of soil. The unconfined compressive strength and California bearing ratio value is increased with the addition of Dunite power. The UCS value is increased from 198.88kPa to 247.29kPa over untreated soil as well as CBR value also increases from 4.61% for unstabilized soil to 8.86% for stabilized soil

Abstract Soil stabilization is the method of improving the physical properties of soil, such as shear strength and bearing capacity of the soil, by using controlled compaction or the addition of admixtures to produce an improved soil material that has all the desired engineering properties. The new technique of soil stabilization uses plastic waste as an alternative material is of outmost crucial since plastic wastes are non-biodegradable and remain intact after being buried in soil for many years. The present study is focused on investigating the effectiveness of utilizing polypropylene clamshell food containers as soil stabilizers. The physical properties of the untreated clayey soil are determined by conducting moisture content, specific gravity, particle size distribution, and the Atterberg limit test. Also, the Standard Proctor compaction test, as well as the unconfined compressive strength test, are carried out to determine the compaction and strength parameters of the soil sample before and after reinforcing with different percentages of polypropylene clamshell food container strips such as 0.4%, 0.8%, and 1.2%. Findings from this study indicate that the addition of polypropylene clamshell food container strips in the clayey soil is capable of becoming a soil stabilizer agent as the optimum compressive strength of the soil was achieved with replacement of 0.8% of plastic strips, along with increasing the Optimum Moisture Content (OMC) while decreasing the Maximum Dry Density (MDD). Successful implementation of polypropylene plastic in soil stabilization can help minimize the volume of plastic waste in the environment, which then leads to developing a sustainable future by utilizing recyclable material as alternative sources in the geotechnical field.

Disposal Problem

In the world full of crises, also the rising demand for PPE suits and masks would lead to another wave of biomedical waste disposition crises. The disposal of thrown away wastes causes a serious issue as the waste are most of the time are non- biodegradable and these are also not fit for incineration. Soil stabilization improves the engineering properties of the weak soil, by proper compaction and additional materials such as lime, concrete, but these materials are becoming expensive day by day, hence plastic by the composition of egg shell powder could enhance the properties and can be a sustainable replacement for lime, concrete, etc. as stabilizer. Through much experimental investigation it has been showed that plastic and egg shell powder can be used as an effective stabilizer with encountering waste disposal problem as well, along with the economical solution for stabilizing weak soil. This PPE stripes/shredding are known for its high strength, low cost, significantly less dangerous for the environment. The combined effect of PPE stripes/shredding along with egg shell powder can enhance engineering properties of soil.
