Recent Developments in Sustainable Infrastructure, 2020

In this study the effectiveness of marble dust to improve the mechanical properties of clayey soil has been studied. Marble has high lime content, which acts as the main factor for soil stabilization. 25-30% marble dust (MD) is generated during marble quarries and stones are cut as a block. In this study marble dust was added in the range of 0-30% to the virgin soil by weight. Various tests like Atterberg's limits, compaction test, and strength tests were performed on untreated soil as well as on treated soil. The results obtained in case of treated soil were compared with the results obtained from the untreated soil. Unconfined compressive strength (UCS) tests were performed at different curing intervals. It was found that the soil strength increased with the increase in marble powder content and curing periods.

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...

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

Expansive soils occurring in arid and semiarid climate regions of the world cause serious problems on civil engineering structures. Such soils swell when given an access to water and shrink when they dry out. Several attempts are being made to control the swell-shrink behavior of these soils. Soil stabilization using chemical admixtures is the oldest and most widespread method of ground improvement. In this study, waste limestone dust and waste dolomitic marble dust, by-products of marble industry, were used for stabilization of expansive soils. The expansive soil is prepared in laboratory as a mixture of kaolinite and bentonite. Waste limestone dust and waste dolomitic marble dust were added to the expansive soil with predetermined percentage of stabilizer varying from 0 to 30 percent. Grain size distribution, consistency limits, chemical and mineralogical composition, swelling percentage, and rate of swell were determined for the samples. Swelling percentage decreased and rate of ...

Results of a laboratory study undertaken to investigate the effect of marble powder on the index properties of clay soil. The clay soil has a poor supporting capacity and large change in volume on variations of moisture content. Such expansive soils may need to be improved to make them suitable for construction activities. The objective of study is to evaluate the feasibility of industrial waste like marble dust as soil stabilization material. To investigate the effect of marble Powder on index properties of clay soil a series of laboratory experiments have been conducted on blackcotton soil samples mixed with 20% to 60% of marble Powder by weight of dry soil. The test results showed a significant change in consistency limits of samples containing marble dust. The liquid limit would decrease from 31.3% to 23.5%. The plasticity index decreased from 11.57% to 4.35%. The CBR test increases from 10.36 to 27.19. From this laboratory investigation it is concluded that the waste material like marble Powder generated from stone industries has a potential to modify the characteristics of expansive clay like clay soil. There is significant improvement in the index properties of the clay soil on addition of marble Powder into it. The expansive behavior of the clay has reduced to a great extent.

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.

An environment friendly and cost effective factor of collapsible soil stabilization with the help of industrial waste has been widely adopted in this research. Buildings which are constructed on collapsible soils are subjected to large deformations and shear failure .Collapsible soil can be broadly categorized as those soils susceptible to a large reduction in volume upon wetting. The mechanism usually involved in rapid volume reduction entails breaking of bonds at coarse particle contacts by weakening of fine-grained materials brought there by surface tension in evaporating water. This research presents the effects of using marble dust on the geotechnical properties of Collapsible soil as a new stabilizing technique. A series of experimental tests are carried for samples of collapsing soil with and without stabilization using marble dust for dry and soaked conditions. The collapsible soil was mixed with marble dust at different contents of (0, 10, 20 ,30%,40% and50%). The results ...
