Sep 25 2019 The waste coconut shell may be utilized to replace natural coarse aggregate. In present study compressive strength of concrete of M - 20 grades has studied by replacing natural coarse aggregates at 0 5 10 20 and 30 by weight with coconut shell. Compressive strength of coconut shell concrete has been evaluated on 7 14 21 and 28 days.
Coconut shell CS is used as aggregate in concrete. Now-a-days there is large use of aggregate is increasing day by day so rather than using coarse aggregate in concrete natural material coconut shell shall be used for some construction. Coconut shell is a waste material from coconut and it is quite strong like aggregate.
Aug 22 2019 Lightweight Concrete Using Coconut Shells as It is concluded that crushed coconut shells are suitable when it is used as substitute for conventional More detailed. A comparative study of concrete properties using coconut shell Chat Onlinefine coarse aggregate in india plants. Strength of coarse aggregates is difficult to measure.
Oct 05 2020 ABSTRACT. This research work reports the investigation carried out to determine the use of coconut shell as an aggregate in light weight concrete. Concrete samples were produced with different mix ratios to determine the best and economic proportions that will give acceptable compressive strengths. Coconut shell aggregate exhibits low impact.
coarse aggregate and coconut shells. • Preparing the concrete cubes with coconut shells and gravel. • Testing those cubes in compression testing PROCEDURE- 3.
Aug 03 2020 coconut shell and coir fiber as partial coarse aggregate replacement in making concrete hollow blocks. Keywords –aggregate ASTM coconut shell coir fiber concrete hollow blocks INTRODUCTION Concrete hollow block CHB is one of the most widely used walling material in building and infrastructure.
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 percentage of coconut shell decreased and under- utilized.
Jun 01 2017 Properties of coconut shell which may make it suitable coarse aggregate for concrete are i its high strength and modulus properties; ii its high lignin content that makes the composites more weather resistant; iii its low cellulose content due to which it absorbs less moisture as compared to other agricultural waste; iv its shells are non-biodegradable; v they can be used readily in concrete which may fulfill almost all the qualities of the original form of concrete;.
Concrete obtained using coconut shell as a coarse aggregate satisfies the minimum requirements of concrete. Coconut shell aggregate resulted acceptable strength which is required for structural concrete. Coconut shell may present itself as a potential material in the field of construction industries.
It was advised that aggregate made from quartzite to be used for the concrete work. The study was made for the properties of concrete with coconut shells as the replacement of aggregate 2. The concrete with normal aggregate as well as coconut shell CS concrete with 10-20 coarse aggregate replacement with coconut shell were made.
4. According to R. Nagalakshmi M25 grade of concrete with cement replaced by fly ash and coarse aggregate by coconut shell and find its compressive tensile strength. 5. According to Sabarudin Bin Mohd he replaced coconut shell and palm kernel shell in place of coarse aggregate in concrete in 0255075 and 100 replacement.
It was observed that the coconut shell has a great potential as a partial replacement of the aggregate in the concrete. The present work is only an accumulation of information about GFRGC and the research work which is already carried out by other researchers. Coarse aggregate were used in proportions of 5 10 15 to replace coarse aggregate.
A large amount of waste coconut shell is generated in Indian temples and industry of coconut product and its disposal need to be addressed. This experimental work will discuss about the effects of replacing coconut shell as coarse aggregate in concrete with 0 10 20 and 30 to produce Eco friendly concrete.
There is no need to treat the coconut shell before use as an aggregate except for water absorption. Coconut shell is compatible with the cement. The 28-day air-dry densities of coconut shell aggregate concrete are less than 2000 kgm3 and these are 184 within the range of structural lightweight concrete. Coconut shell aggregate concrete satisfies the requirements of ASTM C 330.
The paper reports on the performance of M30 grade of concrete mixes containing different ratios of coconut shell having 20 mm maximum size as coarse aggregate.A Study on the Utilization of Coconut Shell as Coarse2019-7-1 developed from coconut shells CS which is locally available in abundance in Kerala it would be a milestone.

Exploratory Study of Coconut Shell as Coarse Aggregate in Concrete Diary of Engineering and Applied sciences vol.3 December 2011. 5 Daniel Yaw Osei Experimental evaluation on coconut shells as total in concrete Global Journal of Engineering Science Invention vol. 2 Issue 5 May 2013.
Correlation between compressive strength and elastic modulus of light weight self-compacting concrete using coconut shell as coarse aggregate.
Results revealed that with 40 replacement of conventional coarse aggregate by coconut shell 7 days compressive strength of concrete decreased by 62.6; whereas decrease in 28 days compressive strength was only 21.5. 40 replacement makes the concrete lighter by 7.47. Further it was revealed that for mix design of concrete of 20 Nmm 2.
