2020

Pertaining to the environmental degradation and policies the utilization of industrial by products and wastes in road pavement is important and increasing to ensure proper productive use of waste material. Contribution of government policies and public awareness also helps in enhancement of both this demand and utilization. All over India there are approximately around 4000 marble mines and 1100 marble processing units are established. Near about 5-6 million tones/year of marble dust is generated and is disposed of on road sides causing environmental degradation, drainage problem and damaging agricultural land. To research the utilization of waste marble powder as a stabilizer to fortify the powerless regular sandy soil. The gradation curve of the sieve analysis shows that the soil is sandy associated with silt of low compressibility (SMSilty Sand). The CBR (California Bearing Ratio) value and UCS (Unconfined Compressive Strength) of soil gives the clear idea about the quality of su...

Sub grade materials are expected to have basic desirable characteristics related to strength, stiffness and permeability. If these properties are not fulfilled, engineers are expected to come up with ground improvement methods. Due to growing cost of traditional stabilizing agents like lime and cement, the need for the economical utilization of industrial and agricultural wastes for beneficial engineering purposes have prompted an investigation into the stabilizing potential of marble dust in highly expansive clay soil. Marble dust is an industrial waste which can be incorporated with road construction materials if it has possesses the desired physical, chemical and mechanical properties. This research work is aimed to evaluate the effect of marble dust for stabilization of expansive clay soil. The laboratory work involved index properties to classify the soil samples. The preliminary investigation of the soil samples showed that it belongs to A-7-5 class of soil in the AASHTO soil classification system. Soils under this class are generally poor for sub grade material. Atterberg limits, Grain size analysis, Specific Gravity, free swell test, compaction, and CBR tests were used to evaluate the geotechnical properties of stabilized soil and to compare with standards. The soil stabilized with marble dust in stepped concentration of 5%, 10%, 15%, 20%, 25% and 30% by dry weight of the soil. Analysis of the results showed that marble dust has a potential to improve the engineering characteristics of expansive soil. Marble dust reduces plasticity index, swelling and OMC with increase in MDD and CBR at higher marble dust contents. From this study it was found out that marble dust stabilized soil for samples 1 and 2 it meets the minimum requirement of ERA pavement manual. However, it has fair to poor as pavement manual specification for use as a sub-grade material in road construction. Soil with 25-30% marble dust combination is found to become the best soil-marble dust combination for both sample 1 and sample 2.

The expansive type of soil known as black cotton soil in India, which shows swelling & shrinkage when it comes in contact with water. So the property the strength and other index properties of this soil are very poor. Soil stabilization with different soil stabilizer shows improvement in engineering & index properties of expansive soil. In this research paper, waste marble powder (by-product of marble industry) used as stabilizer. Marble powder mainly contains high amount of calcium, silica, alumina which aids in the stabilization of the soil. This work shows the determination of the swelling potential of virgin soil as well as when mixed with varying proportion of marble dust (from 10 to 30%).The results obtained in laboratory provide satisfactory reason for using the marble powder as a stabilizer for improving index properties of black cotton soil.

Marble Dust and Foundry Sand are two of the most widely spread and easily available waste materials that are produced by the industries. Marble Dust is a dust that is generated in the process of cutting of marble stone while foundry sand is a waste product of the metal casting industry. In this research work the utilization of marble dust and foundry sand as a soil stabilizing material is tested. Stabilizing the soil is very important part of the construction process. This is because some of the soils do not have the proper strength to bear the load that is being put on them and thus many times lead to a complete collapse of the building. To avoid this situation stabilization is done so that bearing capacity of the soil is increased to withstand the designed load. Lime and cement are the two materials that were mostly used for soil stabilization since many years. But now a day, due to the depletion of the natural resources there is an increase in the utilization of the waste materials for the same. Some of the waste materials used are fly ash, marble dust, foundry sand, rice husk ash etc. These materials not only provide an alternative to the usage of conventional materials, but are also helpful in controlling the environmental pollution. At most of the places these waste materials are dumped into the open area which causes a lot of problem to the people around that area as well as to the workers working at these places. Utilizing these waste materials will not only reduce the pollution but will also reduce the human dependability on the natural resources, thus leading to a more sustainable approach of construction. I. INTRODUCTION Soil is a major component of the earth's surface which sustains life. It is made up by the disintegration of rocks due to various environmental processes like changing weather, volcanic action, erosion of rocks by water etc. Some of the various types of soil that are found in our country are alluvial soil, laterite soil, peaty soil, black cotton soil or expansive soil etc. The type and availability of these soils are based upon the climatic and geographical location of a particular area. Apart from helping the plants grow, soil also helps the humans to carry out all the basic activities on it like travelling, construction, agriculture etc. A developing country like India demands rapid growth in its infrastructure i.e. a proper network of roads and buildings for development. All the constructions related to civil engineering, as like a simple house or a multi-storey building, a road or a highway, everything is built on the soil. It is very important to check all the engineering properties of the soil like the bearing capacity, shear strength etc before starting any construction work on it because all the soils are not suitable for construction always. Before construction of any project, site selection is the foremost objective of engineering department. The main purpose of site selection or investigation is to determine stable and good quality soil where the construction is to be done. It also helps in collecting all the relevant information about soil and its properties. Afterwards, soil with the best quality is selected for construction so that it would result in better structure. Foundation is the main part of any construction and it is totally depending upon the type of soil. Foundation soil is the one that carrying all the loads of structure and good foundation gives more stability and better texture to the construction. There are many types of soil that are found. They are:-1) Sandy 2) Silty 3) Chalky 4) Clayey 5) loamy Soil stabilization is a general term for any physical, chemical, biological, or combined method of changing a natural's oil to meet an engineering purpose. Usually compaction is done to stabilize the soil. Apart from compaction, draining out of the excess water also helps in increasing the stability of the soil. Adding various materials in the soil also helps in stabilizing it. Lime and cement have been the main sources of soil stabilization since many years. But gradually, utilization of cement for stabilization is decreased

The soils which show very high shear strength in a dry state but rapidly lose their strength on wetting are known as collapsible soils. Such rapid and massive loss of strength produces severe distress leading to extensive cracking and differential settlements, instability of building foundations, and even collapse of structures built on these soils. Waste marble dust is an industrial byproduct and is being produced in large quantities globally poses an environmental hazard. Therefore, it is of the utmost need to look for some sustainable solution for its disposal. The present study focused on the mitigation of the collapse potential of CL-ML soil through a physio-chemical process. The soil is sensitive to wetting, warranting its stabilization. Waste marble dust (WMD) in varying percentages was used as an admixture. The study's optimization process showed that geotechnical parameters of collapsible soil improved substantially by adding waste marble dust. Plasticity was reduced wh...

In this paper, marble waste is evaluated as a secondary material to be utilized as potential stabilizer to improve the volume change and strength characteristics of sand-amended expansive soil, proposed as a possible landfill, pavement or sub-base material in a semi-arid climate. An experimental program was conducted on sand-expansive soil enhanced with marble waste, abundantly found as a by-product of construction industry, obtained from two different sources with different gradations, denoted as marble powder (MP) and marble dust (MD). One-dimensional swell, volumetric shrinkage, consolidation, unconfined compressive and flexural strength tests were conducted on expansive soil-sand mixtures with 5, 10 and 20% waste marble inclusions over curing periods of 7, 28 and 90 days. Test results showed that 10% marble powder and 5% marble dust by dry mass were the optimum amounts for mitigating the swell-shrink potential and compression index as well as yielding the highest unconfined compressive and flexural strength values. Moreover, the rate of reduction in swell potential versus the flexural strength over the curing periods studied is highest in 10% MP-and 5% MD-included specimens, the latter being more insensitive to this change. The soil mixtures displayed brittle behavior after marble addition, hence its utilization as a secondary additive to sand-amended expansive soil is recommended for soils exposed to lower flexural loads such as light traffic.

Understanding the behavior of expansive soil and adopting the appropriate control measures should be great for civil engineers. Extensive research has been going on to find the solutions associated with problems of expansive soils. There have been many methods available to control the expansiveness of these soils. The removal of expansive soils and replacement with suitable material has been widely practiced worldwide. Reasonable material is available within economic distances; however, suitable materials is not readily an available in urban areas for borrowing, which has to be hauled from a long distance. Instead of borrowing suitable soil from a long distance away, after stabilization with cost effective and readily available industrial and agricultural waste materials, it is economical to use locally available plastic soil. Such wastage products are also used to minimize environmental hazards such as CO2 in the atmosphere to minimize the percentage of industrial products used for...
