This book was released on 2009 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft clay soil can be categorized as problematic soil. The low strength and high compressibility characteristics the soil had, are the major reasons why a careful design analysis could be taken for any structure built on it. Due to these problems, soil investigation on the basic properties and shear strength of the soil must be carried out. This soft clay study has contributed to local engineering studies regarding the basic soil properties and shear strength in Langgar and Pahang Tua soil, where both are located in Pekan. Attempts were made to analyze the soil samples in laboratory. Overall, from the basic soil properties results, there are strong potential for the soil in Langgar and Pahang Tua to be concluded as soft clay type of soil. From the requirement set by American Association of State Highway and Transportation Officials (AASTHO), both Langgar and Pahang Tua soil samples have been dominant by clay particles with more than 35% passing the No.200 sieve, which are 52% in Langgar and 57% in Pahang Tua. The natural moisture content in Langgar and Pahang Tua soil samples are each 57% and 48% which are within the range of moisture content for soft clay soil. For atterberg limit results, Langgar has liquid limit of 51% and plastic limit of 26%. For Pahang Tua, the liquid limit and plastic limit result are 58% and 27%. Based on plasticity chart, both Langgar and Pahang Tua have been determined to be plotted as clay with high plasticity. The shear strength test results have clearly shown the weakness of Langgar and Pahang Tua soil which are within the strength of a soft clay. Both Langgar and Pahang Tua have 19.18kPa and 21.11kPa of shear strength. The results that have been determined from this study can give an extra dimension and usage for engineers to use for any preliminary design in the area of Pekan. The results data of the basic soil properties and shear strength could also allow a quick and economic alternative in order to design for construction on soft clay soil.

This book was released on 2007 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft clay type of soil is different from other soil type. This is because of its low strength and high compressibility characteristics which make it difficult to get an undisturbed sample to be used in order to conducted laboratory test. Due to this problem the correlation between engineering characteristics and basic properties or between engineering characteristics itself can be useful for engineer in order to do preliminary design. This study has managed to develop some correlations of engineering characteristics for soft clay in Pekan. The data used in this study are obtained from three difference sites which are in Langgar, Permatang Keledang and Tanjung Batu. An attempt was made to correlate Atterberg limit with the shear strength and also shear strength with depth. Overall, the correlations shows that the Atterberg limits value are increasing with moisture content. The shear strength values also increase relatively with the value of plasticity index. The results that have been determined from this study can give an alternative for engineers to use the basic soil properties to predict the strength of the soil. The value for shear strength at certain depth can also be determined from the equations produced. This automatically allows a quick and economic alternative in order to design for construction on soft clay soil. -Author.

This book was released on 2009 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The strength and stability of the soil surface need to be define before any construction begin. The purposes of this study are to obtain the basic characteristic and shear strength of silty clay at the some location in Temerloh district. It has low compressibility and most of the structure constructed on it usually will be affected especially in stabilization and settlement. In order to prevent that from happen, the engineering properties of silty clay must be determined before the beginning of any design work. In this study, some disturbed samples of silty clay were required, taken from 2 different locations which are Kg Buntut Pulau and Kg. Sanggang for soil identification, classification and properties test. For the determination of basic properties of that silty clay, a laboratory test of sieve analysis and Atterberg Limit were conducted in order to get the relationship between moisture content, liquid limit and plasticity index of every sample. Then, the Unconsolidated-Undrained test was choosed as the suitable method of Triaxial Test for determining shear strength parameters for the silty clay. From the result, the moisture content of the sample from both sites is 34.52% and 50.8% respectively. Meanwhile, for the Atterberg limit result, both site recorded the reading of 51.10% and 54.87% respectively for liquid limit and also 25.31% and 28.78% for the plastic limit. Then the value of plasticity index which obtain form the liquid and plastic limit is 25.79% and 26.09%. Then for the particle size distribution test, site A was recorded percentage of silt and clay as the highest with 51% and for same as for site B with 56% of silt and clay for the most dominant particle. The shear strength test results have clearly shown the weakness of Kg Buntut Pulau and Kg. Sanggang soil which are within soft clay soils strength with the average recorded value of 37.91kPa and 26.41kPa respectively. The data and result from this project can be used as a preliminary forecast for further investigation of soil properties and shear strength in the future construction and development.

Available in PDF, EPUB and Kindle. Book excerpt: The main objectives of this research are to determine the plasticity properties and the shear strength properties of lime treated soft clay. The physical properties and shear strength properties of lime treated soft clays are investigated by conducting laboratory test such as atterberg limit test and unconfined compression test. Atterberg limit test have been carried out for 7 days of curing period for the treated clay with the optimum lime content. For unconfined compressive test, the test have been carried out for 7, 14, and 28 days of curing period. For atterberg limit, there is an increment in both plastic and liquid limit of the lime treated soft clay and untreated soft clay. The liquid limits for untreated soil is 66.5% then increase into 73.30% when 20% lime is added. The plastic limit for untreated soil sample is 34.9% before it increase to 38.68% for 20% lime added respectably. This resulted an increment in plasticity index from 31.55% for untreated sample to 34.62% at 20% lime. For unconfined compressive test, the result have shown that there is an increment for the axial stress based on the curing days. The maximum axial stress for the untreated clay is initially 158.47 kN/m2. After added with 20% of lime content, the maximum axial stress is increased to 209.21 kN/m2 for 7 days of curing while for 14 and 28 days, the maximum axial stress are 231.19 kN/m2 and 352.02 kN/m2. It can be conclude that, lime stabilization method can be used as a soil treatment program for soft clay especially for road construction.

Download or read book Investigation on the Undrained Shear Strength of Soft Clay Mixed with Various Percentages of Lime and 6 of Silica Fume written by Kah Seng Leong and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: Difficulties posed by low plasticity soils including silty and sandy clays, silts, and sands are described. The soils considered are not cemented and generally display the dependence between consolidation state and strength necessary to apply such procedures as Stress History and Normalized Soil Engineering Properties (SHANSEP). Unfortunately, these soils are highly susceptible to sampling disturbance because of the unavoidable low effective stress that remains in specimens after sampling. Sampling disturbance obscures consolidation behavior, making it difficult to estimate the in situ overconsolidation ratio. Also, the low compressibility of these materials makes it difficult to clearly define the virgin compression curve. Improvements in interpretation procedures will come only after a sound mechanical description of sampling disturbance has been developed.

Download or read book Ground Improvement written by Professor Jian Chu and published by Elsevier. This book was released on 2005-11-07 with total page 1137 pages. Available in PDF, EPUB and Kindle. Book excerpt: - The first book of its kind, providing over thirty real-life case studies of ground improvement projects selected by the worlds top experts in ground improvement from around the globe. - Volume 3 of the highly regarded Elsevier Geo-engineering book series coordinated by the Series Editor: Professor John A Hudson FREng. - An extremely reader friendly chapter format. - Discusses wider economical and environmental issues facing scientists in the ground improvement.Ground improvement has been both a science and art, with significant developments observed through ancient history. From the use of straw as blended infill with soils for additional strength during the ancient Roman civilizations, and the use of elephants for compaction of earth dams during the early Asian civilizations, the concepts of reinforced earth with geosynthetics, use of electrokinetics and thermal modifications of soils have come a long way. The use of large and stiff stone columns and subsequent sand drains in the past has now been replaced by quicker to install and more effective prefabricated vertical drains, which have also eliminated the need for more expensive soil improvement methods.The early selection and application of the most appropriate ground improvement techniques can improve considerably not only the design and performance of foundations and earth structures, including embankments, cut slopes, roads, railways and tailings dams, but also result in their cost-effectiveness. Ground improvement works have become increasingly challenging when more and more problematic soils and marginal land have to be utilized for infrastructure development.This edited compilation contains a collection of Chapters from invited experts in various areas of ground improvement, who have illustrated the basic concepts and the applications of different ground improvement techniques using real projects that they have been involved in. The case histories from many countries ranging from Asia, America, Australia and Europe are addressed.
