This book was released on 2015 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil stabilization can make the soils becoming more stable. This method is applying admixture on the soil. Lime stabilization enhances engineering properties of soil, including reducing the soil plasticity, increase in optimum moisture content, decrease in maximum dry density and improvement in compaction of soil. Silica fume is utilized as a pozzolanic material in the application of soil stabilization. Silica fume was once considered as non-environmental friendly. Now, it has been adopted as a binder material with cement materials for the application of the soil stabilization. In this research, the materials required are kaolin grade S300, lime and silica fume. The focus of the study is the determinations of the physical properties of the soils tested and the strength of kaolin mixed with 6 % of silica fume and various percentages (3.0 %, 5.0 %, 7.0 % and 9.0 %) of lime. Unconfined compression test is carried out on the kaolin and the mixtures of soil-lime-silica fume to investigate the effect of lime stabilization with silica fume additives on the unconfined compressive strength of the mixtures. Based on the results obtained, all soil samples are indicated as soils with medium plasticity. From 0 % to 9.0 % of lime with 6.0 % of silica fume, the decrease in the maximum dry density is by 5.92 % and the increase in the optimum moisture content is by 23.5 %. Decreases in the coefficient of permeability of the mixtures occur if compared to the coefficient of permeability of kaolin soft clay itself. The optimal percentage of lime-silica fume combination is attained at 5.0 % of lime and 6.0 % of silica fume in order to improve the shear strength of kaolin soft clay. The improvement in shear strength of this stabilized mixture is 29.83 % if compared to the shear strength of the kaolin sample. It can be concluded that lime-silica fume mixture was an effective stabilizer for improving the geotechnical properties of clayey soils.

Book excerpt: Clay soil as known as soft soil present difficulties to geotechnical engineer due to its complex nature and also contain variable materials. This type of soil can be categorized as problematic soil due to its weak properties. As the preliminary stage, soft clay soil did not meet the requirement for construction purpose. This is because the entire load from the top of the building will be transferred to the underlying soil. As we know the strength of soil is weak, without proper design, modification and earthwork, construction problem such as cracking, settlement of building may be occur and the building may collapse within its design life. It is very risky if the construction is still continuing on this type of soil without any remediation or improvement on the soil itself. Therefore, a proper modification for the soil itself is required to alter the soil become stronger; hence meet the requirement to use in construction industry. There are various methods to improve the soil. This research proposes about soil stabilization method that is soft clay soil Kaolin S300 stabilized with various percentages of lime and 4% silica fume. Percentages of lime used are 3%,5%,7% and 9%. While the percentage of silica fume used is fixed that is 4%. The main objectives in this research is to conduct the improvement of undrained shear strength of soft clay soil mixed with various percentages of lime and 4% silica fume. The improvement will be observed based on different percentage of lime. Other physical and mechanical tests that involves in this study are Atterberg Limit, Falling Head, Standard Compaction, Hydrometer, and Specific Gravity, The properties of soil was compared between the kaolin only and different percentages of lime mixed with 4% silica fume. The main test in this research is unconfined compressive test that is to determine the undrained shear strength. From the study, the optimum amount value of lime is 5%. This is because at 5% lime content, the maximum stress achieve is 29.37 kPa which is optimum compared to others percentage. It is shown that, the strength of soft clay is improved by 14.28%. Based on laboratory test result, it can be concluded that soil stabilization by using lime and silica fume can improved the strength of soft clay. Lastly, after all the tests had been done, correlation equation and cohesion value for each test were list out in graph and tabular form as well.

Available in PDF, EPUB and Kindle. Book excerpt: Foundations on Expansive Soils provides the practicing engineer with a summary of the state-of-the-art of expansive soils and practical solutions based on the author's experience. The book is organized into two parts. Part I deals with theory and practice, and summarizes some of the theoretical physical properties of expansive soils. It also discusses various techniques employed to found structures on expansive soils such as drilled pier foundation, mat foundation, moisture control, soil replacement, and chemical stabilization. Topics covered include the origin, mineralogical composition, and the basic structure of expansive soils; the migration of water, swelling potential, and swelling pressure; site investigations and laboratory testing; moisture control; and soil stabilization. Part II presents case studies on the following: distress caused by pier uplift; distress caused by the improper design and construction of a drilled pier foundation system; distress caused by heaving of footing pad and floor slab; distress caused by heaving of continuous footings; and distress caused by a rise of ground water.

Download or read book Fundamentals of Fibre Reinforced Soil Engineering written by Sanjay Kumar Shukla and published by Springer. This book was released on 2017-01-16 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to serve as a one-stop reference on fibre-reinforced soils. Over the past 30-35 years, the engineering behaviour of randomly distributed/oriented fibre-reinforced soil, also called simply fibre-reinforced soil, has been investigated in detail by researchers and engineers worldwide. Waste fibres (plastic waste fibres, old tyre fibres, etc.) create disposal and environmental problems. Utilization of such fibres in construction can help resolve these concerns. Research studies and some field applications have shown that the fibres can be utilized in large quantities in geotechnical and civil engineering applications in a cost-effective and environmentally friendly manner. This book covers a complete description of fibres, their effects when included within a soil or other similar materials such as the fly ash, and their field applications. It gives a detailed view of fibre-reinforced soil engineering. The book will be useful to students, professional, and researchers alike, and can also serve as a text for graduate coursework and professional development programs
