Clay Reinforced with Cocopeat 2INTRODUCTIONBackground InformationThis report paper is about the engineering behaviour of the clay reinforced with cocopeat. Cocopeat is a natural fibre which is made up of husks from coconut. The extraction of coconut fibre from coconut husks produces cocopeat which is 100% natural. Soil is a natural occurring particles of the minerals which is formed through the process of weathering of rocks. The determination of different shape and type of soil can be done through physical processes which may be disintegration or erosion caused by action of the freeze-thaw in the cracking of rocks as well as chemical processes. The soil type formed through chemical processes do not share any similarities with the parent rock whereas the type of soil formed through the physical processes have similarities to the parent rock[CITATION IS113 \l 2057 ]. The composition of the clay soil include crystalline minerals that is formed through the process of chemical weathering of rocks caused by the action of carbon dioxide, oxygen, and water together with the particles having dimensions less than 0.002mm. Clay minerals can be geologically be defined as phyllosilicate having a simple octahedral and tetrahedral arrangement of sheet. The minerals that are phyllosilicate are normally soft because of the modification of the tetrahedral-octahedral layers that are electrically neutral where every layer is joined to the next through the hydrogen forces or Van der Waal’s[CITATION IS215 \l 2057 ]. An example of clay soil is kaolin which is made of minerals of kaolinite through a process of chemical fragmentation of feldspar. In the process of formation of the structural arrangementsby layers, the spaces amid layers between the sheets of stacked tetrahedral-octahedral can be empty or filled with water molecules or cations. This will provide the clay soil with the property of cohesion. The cohesive property represents the strength of the clay soil when
Clay Reinforced with Cocopeat 3water is filled in the spaces that are void hence resulting in negative pressure held by the tension of the capillary[CITATION IS212 \l 2057 ]. Clay soil is said to be liquefiable since when it is partially saturated or fully saturated then it loses its stiffness and strength substantially when stress or forced is applied to it. The water absorption leads to the behaviour of soil plastic which does not disintegrate easily and can be moulded or deformed. As the clay soil’s water holding ability is high, it provides the soil an extra feature of low permeability which results in swelling that will lead to the expansion of the soil making it to become weaker. The clay type of soil provides great challenges to the construction and engineering industries globally due to its inability to carry or hold huge loads of buildings and structures constructed within or above the soil[CITATION Akh13 \l 2057 ]. LITERATURE REVIEW The engineering behaviour of clay reinforced with cocopeat together with the consolidated impacts of the cocopeat are summarized in this section of the paper. This section also focuseson the major objective of this research paper which is how to improve the characteristics of the clay soil by the use of round improvements through the introduction of cocopeat into the clay[CITATION Akt12 \l 2057 ]. Ground Improvement MethodsGround improvement is a process done with an aim of improving the geotechnical features and earthwork of the soil at a particular site. This improvement of the soil can be done through altering the natural features of the soil to improve its performance. Ground can be improved through modification by the use of inclusions or reinforcements into the soil, modification by addition of some materials to the soil, as well as modification without addingany material[CITATION Cho14 \l 2057 ].
Clay Reinforced with Cocopeat 4Some of the ground improvement techniques include drainage, reconsolidation, dewatering, excavation, ground freezing, densification, grouting, and modification of hydraulic flows. The ground improvement can be categorised into physical and chemical modification, modification through reinforcement, confinement, and inclusion, hydraulic modification, or mechanical modification. Some of the factors affecting the choice of soil modification method include economics, environmental concerns, availability of materials, soil properties required, and soil type[CITATION Est10 \l 2057 ]. Characteristics of Clay Reinforced with CocopeatThe impacts of the clay soil reinforced with cocopeat has been investigated by numerous researchers who have been directly involved in construction and engineering of structures on top of the clay soil. The cocopeat was used in the determination of its effect on the clay soil which was gotten from the local farms of India. The sample of the soil was screened, sieved, and broken down so as to acquire a mass that is homogenous. Both the cocopeat content used range from 0 to 1 percent with an addition of 0.2 percent regarding the percentage soil’s dry weight and with a dimension of 20mm, 15mm, and 10mm. The preparation of the samples was done through distributing and mixing the cocopeat randomly all over the clay soil with water added at the optimal quantity gotten from the standard test of proctor. Figure 1 below shows the results for the cocopeat which was gotten after the above experiment was carried out:
