TL;DR: In this paper, the effect of Silica fume on engineering characteristics of expansive clay like Black Cotton Soil has been presented and a series of laboratory experiment has been conducted on black cotton soil blended with Silica Fume content from 5% to 20% by weight of dry soil.
Abstract: Due to rapid growth of urbanization and industrialization, minimization of industrial waste is serious problem in present days. To encounter this ennovative and nontraditional research on waste utilization is gaining importances now a days. Soil improvement using the waste material like Slags,Rice husk ash,Silica fume etc.,in geotechnical engineering has been recommanded from environmental point of view. The main objective of this study is to evaluate the feasibility of using Silica fume as soil stabilization material. In this paper the effect of Silica fume on engineering characteristics of expansive clay like Black Cotton Soil has been presented. A series of laboratory experiment has been conducted on black cotton soil blended with Silica fume content from 5% to 20% by weight of dry soil. The experimental results showed a significant increase in California bearing ratio and Unconfined compressive strength.The Differential free swell of the clay is reduced from 50% to 7% with increase in Silica fume content from 0% to 20% respectively.The Proctor compaction results showed a small decrease in Maximum dry density and increase in Optimum moisture content. From this investigation it can be concluded that the Silica fume as a potential to improve the characteristics of black cotton soil.

TL;DR: In this paper, the performance of hexahydrated magnesium chloride (MgCl2· 6H2O) as a chemical stabilizer of granular road surfaces was evaluated in arid and semiarid regions in the Atacama Desert in northern Chile.
Abstract: The performance was evaluated of hexahydrated magnesium chloride (MgCl2· 6H2O) as a chemical stabilizer of granular road surfaces. MgCl2· 6H2O is a salt with properties that are useful for chemical stabilization of granular road surfaces, such as its capacity to absorb and retain humidity from its surrounding environment, increase water surface tension, and decrease water vapor pressure. Its effect on the physical and mechanical properties of soils was evaluated in laboratory, and its functional performance and durability were evaluated in field trials. Field trials were performed in arid and semiarid regions in the Atacama Desert in northern Chile. Field results showed that roads stabilized with MgCl2· 6H2O remain free of dust and corrugations and exhibit a considerable reduction in pot-holes and surface erosion. The period of effectiveness for MgCl2· 6H2O has proven to be more than 2 years, without any type of road maintenance.

TL;DR: In this paper, the effect of Na + modified montmorillonite nanoclay on clay engineering properties has been examined in a study, and the obtained results show that liquid and plastic limits rise with increasing nanopoclay content.
Abstract: Nanoparticles are one of the newest materials that can be used in soil stabilization. The effect of Na + modified montmorillonite nanoclay on clay engineering properties has been examined in this study. At first, it is used for dispersing nanoparticles into soil and preparing samples. Used nanoclay content by dry weight percentage of soil is 0.5, 1, 1.5 and 2%. Variations caused by increasing nanoclay content were studied. Soil compaction test was performed in order to achieve maximum specific weight and optimum moisture content. Tests were conducted using nanoclay and then without it. The obtained results show that liquid and plastic limits rise with increasing nanoclay content. In the uniaxial and CBR tests, the highest soil resistivity can be seen by adding 1.5% of nanoclay. Low percentage of nanoclay generally improves the soil properties. DOI: http://dx.doi.org/10.3126/ijls.v9i4.12670
