Coarse Aggregate: The used aggregates were in the range of 20 mm to 25mm IS sieve size and it collects Key Words: Coarse aggregate, Coconut Shell, from the local crusher. The tests conducted on Compressive Strength, Splitting Tensile strength, coarse aggregate include specific gravity, water Concrete Cubes, Concrete Cylinders.
The mix ratio 1:1:1; 1:2:2 gave compressive strength of 16N/mm2 and 7.71N/mm2 at 28day strength test respectively. In addition, Partial replacement of normal coarse aggregate with coconut shell was also carried out using the following percentages of 0%, 25%, 50%, 75% and 100% for a mix ratio1:2:4 .

source of structural aggregate material. It is becoming more difficult to find natural resources. Therefore the coconut shell as partial replacement for coarse aggregate in concrete is studied. The density, slump and compressive strength of concrete are tested. The replacement of coarse aggregate by coconut shell by 0%, 10%, 20% and 30%.
Abstract––Properties of concrete with coconut shells (CS) as aggregate replacement were studied. Control concrete with normal aggregate and CS concrete with 10 - 20% coarse aggregate replacement with CS were made. Two mixes with CS and fly ash were also made to investigate fly ash effect on CS replaced concretes.

coarse aggregate in solving part of natural aggregate. The various waste materials are used such as coconut shell, cockle shell, periwinkle shell, foundry sand etc. so here in my project I will use coconut shell waste as replacement of coarse aggregate by different percentage for making concrete of different grade like M-20.
coconut shell concrete with the replacement of 16%, 18.5% and 20% by coarse aggregate By testing the concrete cubes, at 28th day 16% replacement of coarse aggregate by coconut shell shows that the strength of the coconut shell concrete was decreased by 2.15% from control mix. Similarly for 18.5% and 20%
Coconut shell as a completely substitution in the place of coarse aggregate may totally effective for designers in construction industry. The coconut shell concrete is a …
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 N/mm 2 ...
Properties of concrete with coconut shells (CS) as aggregate replacement were studied. Control concrete with normal aggregate and CS concrete with 10-20% coarse aggregate replacement with CS were ...

M20 mix design was carried out for control mix (i.e. without coconut shell) according to Indian standards .Detailed procedure of mix design is provided in Annexure A.The concrete mix was designed for slump of 60 mm.Using same mix design, coconut shell concrete was prepared by replacement of conventional crushed coarse aggregate (CA) with waste coconut shell (CS).
using coconut shell as partial replacement of coarse aggregate in concrete and determining its compressive strength and density. Until now, Industrial by products and domestic wastes has been utilized in concrete, but the use of agricultural waste in concrete is in its infancy stage. Coconut shell is an agricultural waste.
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.
