The average fresh concrete density and 28-day cube compressive strength of the concrete using coconut shell aggregate were 1975 kgm 3 and 19.1 Nmm 2
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, crushing, and abrasion values of 1.3, 1.16
Hence, there is the need to study the feasibility of Dandagala et al2014 have made laboratory investigation on green coconut shells and matured coconut fibre as the aggregates coconut shell in concrete, an alternative low cost building material for concrete preparation in the future research programme. and reached at following findings that coconut shell can be used as REFERENCES full
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.
experimental assessment on coconut shells as aggregate in concrete. The results of his study showed that concrete produced by replacing 18.5 of the crushed granite by coconut shells can be used in reinforced concrete construction. He concluded that the use of coconut shells as partial replacement for conventional aggregates should be ...
The results also indicated cost reduction of 30 and 42 for concrete produced from coconut shells and palm kernel shells, respectively. Considering the strengtheconomy ratio, it was concluded that coconut shells were more suitable than palm kernel shells when used as substitute for conventional aggregates in concrete production. r 2005 ...
Oct 01, 2011 The Behavior of Reinforced Concrete Beams with Coconut Shell as Coarse Aggregates CIVIL Project aims at analyzing flexural and compressive strength characteristics of concrete produced using crushed, granular coconut as substitutes for conventional coarse aggregate with partial replacement using M30 grade concrete. Beams are casted, tested and their physical and mechanical
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 ...
Sep 24, 2020 A total of five mixtures were made with coconut shell ash replacing Portland cement up to 20. Results from this paper showed that coconut shell ash can be incorporated into concrete mixtures to reduce its embodied carbon. A reduction in embodied carbon of about 15 was achieved when 20 of Portland cement was replaced with coconut shell ash.
Sep 03, 2020 But its high strength modulus, natural shell structure and the non-biodegradable pentosans chemical constituents can be utilised for using coconut shell as an alternative for coarse aggregates, reinforcement, filler, thermal insulating material, hollow structure provider, etc., in building blocks and concrete technology.
Jul 23, 2017 The main purposes of using coarse aggregate in concrete is for its durability and strength. Stronger the coarse aggregate greater will be the crushing strength of concrete. Generally used coarse aggregate in making concrete is Crushed Stone. Cru...

Coconut sh ell CS is one of the agricultural waste and made customary in the manufacturing of coconut shell aggregate concrete CSAC by researcher almost one decade too 12-26. Most of the research results on coconut shell used concrete were encouraged to use it in the field applications concrete as well.
In this work we will discuss about the replacement of coarse aggregate and cement with coconut shells and fly ash in this project, we know that the strength of both coarse aggregate and cement mixture now we will check the concrete, then we will add the coconut shells and the 15 fly ash and prepare the concrete.
waste, groundnut shell, waste glass, broken bricks are some examples of replacing aggregates in concrete4. Coconut shell is categorized as light weight aggregate. The coconut shell when dried contains cellulose, lignin, pentosans and ash in varying percentage 5. In Asia, the construction
For coconut shell aggregate to be used efficiently for construction purposes, it is imperative to investigateitsproperties. Therefore, this study examined the effect of coconut shell as fine and coarse aggregate replacement on the behavior of concrete with respect to some vital properties. The coconut shell concrete was designed for

Some of the interesting insights of the study are a coconut shells and fibers are applicable as a partial substitute as coarse aggregates for concrete hollow blocks. b the good indicators of coconut shell and fiber quality as aggregate of concrete hollow blocks are particles, shape, and texture, resistance to crushing, absorption and ...
1.2.1 Coconut Shell As Aggregate Coconut shell particles are used as reinforcing material for investigation. Shell particles of size between 20 mm 600 are prepared in grinding machine. Coconut shell aggregates are potential candidates for the development of new composites because of their high strength and modulus properties.
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
Concrete made from coconut shell waste as coarse aggregate will be studied for compressive strength, tensile strength and flexural strength. the percentage replacement will be 0, 10, 20 and 30 with natural coarse aggregates and replacement of 10 various size of coconut shell in concrete. the replacement 10 of coconut shell and added coir ...
2. Coconut shell as coarse aggregate The concrete obtained using Coconut Shell aggregates satisfies the minimum necessities of concrete. Coconut Shell concrete has superior workability because of the smooth surface on one side of the shells. The impact resistance of Coconut Shell concrete is high when compared with conventional concrete.
