Clay Reinforced with Cocopeat2INTRODUCTIONBackground 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 ofcoconut fibre from coconut husks produces cocopeat which is 100% natural. Soil is a naturaloccurring particles of the minerals which is formed through the process of weathering ofrocks. The determination of different shape and type of soil can be done through physicalprocesses which may be disintegration or erosion caused by action of the freeze-thaw in thecracking of rocks as well as chemical processes. The soil type formed through chemicalprocesses do not share any similarities with the parent rock whereas the type of soil formedthrough 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 theprocess of chemical weathering of rocks caused by the action of carbon dioxide, oxygen, andwater together with the particles having dimensions less than 0.002mm. Clay minerals can begeologically be defined as phyllosilicate having a simple octahedral and tetrahedralarrangement of sheet. The minerals that are phyllosilicate are normally soft because of themodification of the tetrahedral-octahedral layers that are electrically neutral where everylayer is joined to the next through the hydrogen forces or Van der Waal’s[CITATION IS215 \l2057 ].An example of clay soil is kaolin which is made of minerals of kaolinite through a process ofchemical 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 beempty or filled with water molecules or cations. This will provide the clay soil with theproperty of cohesion. The cohesive property represents the strength of the clay soil when
Clay Reinforced with Cocopeat3water is filled in the spaces that are void hence resulting in negative pressure held by thetension of the capillary[CITATION IS212 \l 2057 ]. Clay soil is said to be liquefiablesince whenit is partially saturated or fully saturated then it loses its stiffness and strength substantiallywhen stress or forced is applied to it.The water absorption leads to the behaviour of soil plastic which does not disintegrate easilyand can be moulded or deformed. As the clay soil’s water holding ability is high, it providesthe soil an extra feature of low permeability which results in swelling that will lead to theexpansion of the soil making it to become weaker. The clay type of soil provides greatchallenges to the construction and engineering industries globally due to its inability to carryor hold huge loads of buildings and structures constructed within or above the soil[CITATIONAkh13 \l 2057 ].LITERATURE REVIEWThe engineering behaviour of clay reinforced with cocopeat together with the consolidatedimpacts 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 ofthe clay soil by the use of round improvements through the introduction of cocopeat into theclay[CITATION Akt12 \l 2057 ].Ground Improvement MethodsGround improvement is a process done with an aim of improving the geotechnical featuresand earthwork of the soil at a particular site. This improvement of the soil can be donethrough altering the natural features of the soil to improve its performance. Ground can beimproved 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 Cocopeat4Some 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, ormechanical modification. Some of the factors affecting the choice of soil modificationmethod include economics, environmental concerns, availability of materials, soil propertiesrequired, 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 numerousresearchers who have been directly involved in construction and engineering of structures ontop of the clay soil. The cocopeat was used in the determination of its effect on the clay soilwhich 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 usedrange from 0 to 1 percent with an addition of 0.2 percent regarding the percentage soil’s dryweight and with a dimension of 20mm, 15mm, and 10mm. The preparation of the sampleswas done through distributing and mixing the cocopeat randomly all over the clay soil withwater 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 aboveexperiment was carried out:
