Abstract The effect of coconut shell and its ash has been investigated and the experiments have been done to utilize these waste materials with concrete as a partial replacement for coarse aggregate and cement. The coconut shell in the form of aggregate is a material which can be a substitute for coarse aggregate in concrete.

of coconut shell as coarse aggregate in concrete by determining its compressive strength and durability. c. To investigate the effect of the combination of coconut shell as coarse aggregate in concrete content and length to the workability as lightweight aggregate in concrete and also the mechanical properties mentioned above.
Oct 05, 2020 Coconut shell aggregate exhibits low impact, crushing, and abrasion values of 1.3, 1.16 and 2.23 respectively compared with normal aggregate with 19.23, 25.60 and 27.67 respectively. Coconut shell, however, has high percentage of water absorption capacity, elongation index and flakiness index of 23.72, 26.69 and 86.12 respectively ...
and 42 for concrete produced from coconut shell and palm kernel shell respectively 6,7. Siti Aminah Bt Tukiman and Sabarudin Bin Mohd 2009 replaced the coarse aggregate by coconut shell and grained palm kernel in their study. Percentage of replacement by coconut shell were 0, 25, 50, 75 and 100 respectively.
Nov 11, 2020 Usage of coconut shell as coarse aggregate in concrete brings a drastic change in concrete technology because the rigidity and impact strength of coconut shell is high. Additionally, the practice of coconut shell in concrete as coarse aggregate not only reducing the problem of waste disposal but also reducing the concrete cost which makes it ...
Aug 29, 2017 AIMS OF THE PROJECTA 1.To determine various alternatives available for coarse aggregate. 2.To carryout a detail analysis on coconut shells as a coarse aggregate in concrete. 3.To prepare a methodology for the project amp its analysis. 4.To enlist advantages amp short comes of coconut shell as a coarse aggregate material. 5.To ...
Nov 24, 2020 The seven days compressive strength of concrete replaced with 0, 5 and 10 of coconut shell ash as fine aggregate along with PPC and PSC was found to be 23.70, 21.33, 18.22, 24.74, 23.70 and 22.22 Nmm 2, respectively. The 28 days compressive strength test of concrete replaced with 0, 5 and 10 coconut shell ash as fine aggregate along with PPC ...
research regarding the use of green coconut tender coconut Shelke et al 2014 have reviewed coconut shell as partial shell and matured coconut husk as fine or coarse aggregates in replacement for coarse aggregate and they made the following concrete preparation should be done so as to utilize these vast inference that the increase in ...
Jun 01, 2017 Using same mix design, coconut shell concrete was prepared by replacement of conventional crushed coarse aggregate CA with waste coconut shell CS. Coconut shell replaced conventional aggregate by 10, 20, 30 and 40 respectively by volume and the effect on compressive strength and density of concrete was observed.
Normal aggregate, that is, crushed blue granite of maximum size 20 mm was used as coarse aggregate. Well graded river sand passing through 4.75 mm was used as fine aggregate. The specific gravities of coarse and fine aggregates were 2.65 and 2.63 respectively. Coconut shells which were already broken into two pieces were
the coconut shell is produced about 3.18 million tonnes 6. In this study the coarse aggregate is replaced by coconut shell in M15, M20, and M25 grades of concrete of 16, 18.5, and 20 each and compressive strength have been found out. From the results it have been concluded that coconut shell can be used as structural concrete and it leads
Research material are cement, natural fine aggregate , coarse aggregate, water and coconut shell. 4.2 Coconut Shell Coconut shell is obtained from temples etc. they were sun dried for minimum 1 month before using crushed manually. The particle size of the coconut shell range from 5mm to 20mm. Cement- Ordinary Portland cement of 53 grade
Coconut shell aggregates Courtesy by review paper parag . s SATISH SHINDE, RAMIZ SAYED,2016 In this paper authors mainly discussed about basic things needed to make human alive like meal, lodging and clothes . They replaced M20 grade concrete by coconut shell as a coarse cluster .
Two different mixes are developed in this study, one with coconut shell as coarse aggregate CSF, and the other with coconut shell and conventional aggregate and as coarse aggregates CSP. The work investigates the benefits of polypropylene fibre addition at 0.25, 0.50, 0.75 and 1.0 by volume of concrete on the engineering properties of ...
Interpretation Fine aggregate sand was uniformly and well graded because C u and Cc lied within the accepted range in accordance to BS 1377 Part2 1990. Potential Of Coconut Shell Ash As Partial Replacement Of Ordinary Portland Cement In Concrete
In this project Fine aggregate is replaced by Quarry dust of 30 along with the partial replacement of coarse aggregate with coconut shell. The coarse aggregate is replaced with 10 , 20, 30 and 40 by coconut shell. The design Mix used for the project is M20 grade 11.53 with WC Ratio 0.5.The Conventional concrete and Coconut shell ...
behaviors of reinforced beam with coconut shell are closely equivalent with using natural aggregates. 9 have studied the properties of concrete that using coconut shell as coarse aggregate and the result is the compressive strength is decrease as the percentage of coconut shell increase.
modified with coconut shell aggregate. In order to test the above properties and compare with that of concrete without any coconut shell aggregate, a control concrete mix was designed as per IS 10262 2009 8 for concrete of grade of M20. Based on the mix design, a mix ratio of 1 1.63 3.13 with water to cement ratio of 0.5 was adopted.
coconut shells and fibers as an aggregate. Analyze the performance and the effectiveness of the coconut shells and fibers as aggregates in concrete hollow blocks in terms of physical properties like color, texture, size, and density and by mechanical properties like compressive strength, modulus
Feb 21, 2017 Potable water was used for mixing and curing Cement Ordinary Portland cement 53 grade was used Fine Aggregate Naturally available fine aggregate from River Coarse Aggregate Crushed granite was used as coarse aggregate of size 20mm and 10mm both. Coconut Shell In this work coconut shell was used as partial replacement of coarse aggregate .
crushing value ACV for coarse aggregate is 21.84 and 4.71 for coconut shell.
