Clay Soil Reinforced with Cocopeat 2INTRODUCTIONProblem StatementClay soil is a cohesive soil with high compressibility and low permeability. This type of soil shrink under dry condition and swells in a wet condition. Clay soil is not appropriate for the majority of the projects of construction since it may lead to the foundation to easily crack leading to the cracking of wall. There is need of using a deep foundation like piling to prevent cracking of foundation. Piling is normally used in local industries of construction because of soft clay soil that is weak found in most sections of Brunei Darussalam. There have been numerous research on ground improvement in Brunei with an aim of widening treatment techniques of the clay soil to improve its performance[ CITATION Akh13 \l 2057 ]. Through the process of soil stabilization, the issue of settlement can be prevented from happening during construction. The swelling and shrinkage of the soil can be minimizedhence improving the soil stability for construction of structures. In this project, the soil improvement method discussed is the use of fibres to improve the characteristics of clay soil. The fibres will prevent the cracking of clay soil during construction hence minimizing the useof gravel and sand due to their high cost. In Brunei, the clay soil is not used in the construction rather it is excavated during construction and thrown away to a wasteland, the use of cocopeat will encourage the clay soil to be improved and effective for construction purposes. The cocopeat inclusions are cheaper and readily available since they are gotten from the coconut husk[ CITATION Cho14 \l 2057 ]. LITERATURE REVIEWThe previous research on reinforcement of soil with cocopeat and the consolidation effects of clay soil are summarized in this section which majorly focuses on the techniques, procedures as well as the results.
Clay Soil Reinforced with Cocopeat 3Stress-Strain Behaviour of Coir Fibre Reinforced Clay soilUnreinforced clay soil specimens prepared at 17.8kN/m3 of dry unit weight portrayed a very brittle behaviour with 0.9% failure. The specimens were made with the coir fibre content of 1.6%, 0.8%, and 0.4%. The full consolidation was assumed to occur after the level of water in the burette which is joined to the valve for drainage becomes constant. The resultsof the compaction show that the optimum content of moisture of the reinforced clay with untreated and treated coir fibre increases with an increase in the content of coir fibre[ CITATION Kan14 \l 2057 ]. The optimum moisture content of clay was 12%. The stress-strain behaviour of reinforced clay with diverse percentages of coir fibre is as shown in figure 1 below. The inclusion of CCL4 treated coir fibre to the clay resulted in greater frictional angle and cohesion improvement.Mechanical Properties of Human Hair reinforced Clay soilSamples that are saturated were prepared for triaxial compression and conventional consolidation test. For the samples preparation, there was a consideration of the technique of slurry. The characteristic of the human hair strength was then determined by the test of tensilestrength. The mechanical and physical properties of the used human hair are as shown in the figure below. When samples that are saturated are tested in the triaxial apparatus by the application of the back pressure, the method may take a long duration in case of longer
