Soil stabilization means alteration of the soils properties to meet the specified engineering requirements. Methods for the stabilization are compaction and use of admixtures. Lime, Cement was commonly used as stabilizer for altering the properties of soils. From the recent studies it is observed that, solid waste materials such as flyash, rice husk ash are used for this intended purpose with or without lime or cement. Disposal of these waste materials is essential as these are causing hazardous effects on the environment. With the same intention literature review was undertaken on utilization of solid waste materials for the stabilization of soils and same is presented here. © 2012 ejge. Source

In the present study, GPS, GIS, and remote sensing techniques were employed for identifying the suitable locations to set up micro hydropower stations on the major distributory (D-83) of Kakatiya main canal on Godavari river, Andhra Pradesh, India. The study deals with evolving the geomatic approach to identify suitable locations. Canal plan and profile have been identified by using toposheets and contours of canal area with one kilometer buffer on both sides are generated in GIS environment. Identification of suitable locations for setting up hydropower stations is done by integrating multisource datasets in GIS platform. Twenty-six locations of suitable sites along the total length of the D-83 canal are identified as suitable to set up small power plants. Heads of 1.219 m, 1.829 m, 2.438 m, 3.048 m, and 3.657 m along the total length of the D-83 canal have been identified as suitable to set up small power plants. © 2013 American Society of Civil Engineers.

Due to the massive growth of Infrastructure projects, conventional construction materials are diminishing day by day or found short in supply at various locations in the country. On the other hand, large quantity of waste materials produced from the different industries like flyash, ggbs, rice husk ash, paper mill slag, etc. creates a potential negative impact on the environmental causing air pollution, water pollution affecting the local ecosystem, and hence safe disposal of these waste materials is required. Utilizing some of these materials as alternative materials for the construction in no doubt is a best solution. Hence an attempt is made to justify the use of rice husk ash by mixing it with lime for stabilization of black cotton soil. This paper highlights the effectiveness of using rice husk ash (RHA) as a puzzuolanae to enhance the lime treatment of soil. Laboratory test results presents the influence of different mix proportions of lime and RHA on compaction, strength properties of soil. It is observed that, addition of RHA enhances not only the strength development but also the durability of lime stabilized soil. © Research India Publications. Source

Expansive soils are clays or silts which are widely distributed in India have a tendency for volume changes due to change in moisture content. Also exhibits several undesirable features like very low bearing capacity, high compressibility. For such soil, replacing with non expansive soil may offer a simple solution to remove these problems. Such soils when used as backfill behind retaining walls often create numerous problems. However, as conventional backfill materials are becoming more scarce and costly, therefore efforts are made to use recycled, secondary material to produce commercially viable fill materials.(88) This paper described how the swelling soils such as black cotton soil were artificially made and mixed with granulated waste of Expanded polystyrene (EPS) in the laboratory. For experimentation we performed test on four samples of soil with varying percentages of prepuff EPS beads. A series of swell pressure and consistency tests are performed on these samples. The results obtained shows, the significant reduction in the volume change behavior of soils. Also the shear tests are performed to check the strength of soil. The results show that inclusion of EPS not shows significant effect on strength, and observed that as the increase quantity of beads reduce the density of fill material, which decrease the strength of soil. Also increases compressibility of mix because of compressible nature of EPS beads. Hence it is suggested that the use of EPS restricted up to certain extent.(142) The objective of the proposed work to prepared the soil EPS Geofoam mix at optimum moisture content that will ensure minimum future settlements, swelling potential or lateral earth pressures Which offers sustainable solution for EPS industries.(36) © Research India Publications.
