Excessive use of materials, leads to industrialization, which has an adverse impact on the environment. From industries, large amount of chemicals or other suspended particles as a waste are produced, which are mostly dumped that acquires large space leading to deterioration of soil properties. So, we should use these waste for some constructive or useful purposes. As steel industry releases waste with some good engineering properties so, we can use this type of waste with soil which has low strength and does not have good engineering properties. Various techniques are available like soil stabilization, providing reinforcement etc. to improve load bearing capacity of soil. Soil stabilization is one of the modification techniques used to improve the geotechnical properties of soil and has become the major practice in construction engineering which enables the effective utilization of industrial wastes as a stabilizer. This technique becomes more popular because of its easy availability and adaptability. In this study, the steel slag (an industrial waste) is mixed with Clay(CI), Lateritic(A-7-6(5)) , Black cotton clay soil to enhance its strength properties and make them more suitable for use. In this way industrial waste can be reduced economically.

Black Cotton Soils

Expansive Black cotton clay soils are widely distributed worldwide, and are a significant damage to infrastructure and buildigs.It is a common practice around the world to stabilize black cotton soil using fly ash to improve the strength of stabilized sub- base and sub grade soil. Soil stabilization is the improvement of strength or bearing capacity of soil by controlled compaction, proportioning or addition of suitable admixtures or stabilizers. The Black cotton soils are extremely hard when dry, but lose its strength fully when in wet condition. In monsoon they guzzle water and swell and in summer they shrink on evaporation of water from there. Because of its high Swelling and shrinkage characteristics the black cotton soils has been a challenge to the highway engineers.So in this research paper fly ash has been used to improve the various strength properties of natural black cotton soil.The objective of this research paper is to improve the engineering properties of black cotton soil by adding different percentage of fly ash by the weight of soil and make it suitable for construction. A series of standard Proctor tests (for calculation of MDD and OMC) and California Bearing Ratio (C.B.R) tests are conducted on both raw Black cotton soil and mixed soil with different percentages of fly ash (5%, 10%, 20%, 30%) by weight. A comparison between properties of raw black cotton soil, black cotton soil mixed with fly ash are performed .It is found that the properties of black cotton soil mixed with fly ash are suitably enhanced.

Expansive clay soils are geotechnically problematic in nature as they possess less shear strength, high compressibility and low permeability. This research work was carried out with a view to improve index and engineering properties of expansive soil by stabilizing it with industrial wastes and geopolymers. The industrial wastes such as fly ash, silica fume and sodium-hydroxide were used for the stabilization of expansive soil. the virgin clay soil was tested for its index properties, compaction characteristics and shear strength determination. the stabilization of clay is made by adding and mixing those materials by varying its percentage. In the stabilization of soil with sodium hydroxide, an attempt has been made to study the effect of its molarity on the various properties of the soil. The clay soil stabilized with various materials was also tested for the same properties and that results were compared with that of virgin soil to find the effect of stabilization.

Abstract Soil is the most important and basic element of earth. In India which have more type of soil which have low or high bearing capacity like black cotton soil which have high montmorillonite and kalinite. These are those type of soil which have high shrinkage and swelling property. This type of soil cannot withstand heavy load. So, to overcome such problem treatment of soil is needed to be done using plastic materials or volcanic ash, cement kiln dust(CKD) particles for stabilizing this soil. Soil stabilization is the process which improve the physical effects of soil shearing and bearing capacity which is use of adding the admixture like cement, fly ash, lime volcanic ash CKD. Engineers are develop new technique for soil stabilization. It is really big deal to use these type of waste to stabilization of soil. India is developing country build new building and break the old building. All this process many type of waste are generate and in Indian survey nearly 7.46 million tonnes of hazardous waste is generated in India annually So the engineers are think the all waste are used in soil stabilization This paper write for two reason, one is recycle the waste materials and other one is increase the soil stabilize. Some type of industrial waste are including the gravel and dirt concrete and masonry, oils, metals, industrial waste like gasses or solids and also count vegetables matters from restaurants. In other words the industrials waste is two type one is non-hazardous and 2nd is hazardous

Expansive soil deposits mostly appear in arid and semi-arid areas of the world and they pose severe difficulties to engineering constructions as they possess higher tendency to heave in the course of moist season and shrink at summer season. Construction in such highly expansive strata can be done by adopting ground modification techniques like soil stabilization, Vertical drains, inducing reinforcement in to soil etc., On the other hand with rapid industrial growth more quantity of industrial waste will be generated which will trigger several environmental issues when it is dumped in to environment. Utilization of industrial waste in construction industry without compromising in strength criteria is the best possible option for the engineers as the waste is used as construction material there will be no need for dumping yards, biodiversities can be protected, strength properties of the soil can be enhanced and hydraulic properties can also be modified by treating soil with industrial wastes. As the river sand can be partially replaced by some of the industrial wastes requirement for natural sand can be reduced which will not only economise the construction cost but also preserves the natural resources. The present study was carried out to assess the behaviour of coir pith treated black cotton soils. Due to increase in the natural fibres in many industries the waste produced from the coir industry is increasing, if proper care is not taken these waste may create severe effects on environment .To avoid disposal of this waste directly into environment it is better to use the waste in construction industry is a better option. But before adopting such practices proper studies are to be done to check whether these materials are suitable for treating the soils are not .In the present study by adding various proportions of coir pith Swell, strength characteristics of soil where compared for obtaining the optimum Replacement percentage

AbstractDamages and economical losses due to problematic soils have caused researchers to conduct many studies for the stabilization of these soils within years. Especially, the use of fly ashes in soil stabilization provides great benefits in contributing to the economy, as well as decreasing the environmental pollution. In the present study, the stabilization characteristics of soil-fly ash mixtures were evaluated in terms of Atterberg limits, compaction characteristics, swell potential and unconfined compressive strength with curing effect. To determine these effects, Catalagzi and Soma fly ashes obtained from Turkey were used in different proportions by weight for stabilization of clay soil samples. It was found that the plasticity index of the soils decreased considerably with the addition of fly ashes, while the strength improved and swell potential decreased. The decreasing trend in the swell percentage and swell pressure values decelerated especially after 25% fly ash additive content and negligible changes occurred. Similar behavior was observed in strength tests. Experimental results show that swelling and strength properties of the soils could be improved by using fly ash and Soma fly ash is far more effective than Catalagzi fly ash.
