· 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 indiors of coconut shell and fiber quality as aggregate of concrete hollow blocks are particles, shape, and texture, resistance to crushing, absorption and ...

Two different mixes are developed, one with coconut shell and the other with conventional aggregate and coconut shell as coarse aggregate. The cement content is replaced with class F fly ash at 0%, 10%, 20% and 30% by weight. The test result shows that the coconut shell concrete produced with 10% fly ash has recorded higher compressive, tensile strength than other proportions. Fly ash ...
the coconut shell is produced about million tonnes [6]. In this study the coarse aggregate is replaced by coconut shell in M15, M20, and M25 grades of concrete of 16%, %, 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 ...
Oil palm shell (OPS) is a waste from the agricultural sector and is available in large quantities in the tropical regions. This paper investigates the effect of the replacement of normal weight coarse aggregate by oil palm shells on the compressive strength, density, modulus of elasticity, workability and water absorption. The gradation of substitution was 0, 28, 55, 83 and 100 .
Two different mixes were developed, one with coconut shell only as coarse aggregates, and the other with the combination of both conventional aggregates and coconut shell as coarse aggregates. The cement content was replaced with class F fly ash at 10% by weight in the concrete mixes.

replacing coconut shell for coarse aggregate. 25% and 50% of coarse aggregate replaceme nt prepared by binding constantly along with water in the ratio of per all mixes, density, wor kability and water adsorption. One week, two weeks and four weeks were determined compressive strength, tensile strength and flexural strength. PARAG S. KAM BLI, SANDHYA R. MATHAPATI (2014) The goal of the ...
coarse aggregate with coconut shell aggregate is determined from the study. Coarse aggregate made from coconut shells were used in proportions of 5%, 10%, 15%, 20%, 25%, 30% and 35% to replace coarse aggregate in conventional concrete. A constant water to cement ratio of was used throughout the study. Tests were carried out to determine the compressive strength, split tensile .
aggregates. Hence we make use of coconut shell as a partial substitute to coarse aggregate. In this experimental investigation, the coconut shell used as a light weight aggregate in concrete, the properties of coconut shell concrete examined, Control concrete with normal aggregate and Partially replaced coconut shell concrete with 10 30% coarse
Thus, in this study will replace part of the coarse aggregate with coconut shell with percentage 0%, 2,5%, 5%, 7,5%, 10% and partially replace cement with coconut shell ash with percentage 0%, 2,5%, 5%, 7,5%.

India is the third largest coconut cultivating country in the world. South India states are the predominant coconut cultivating area in India. Coconut shell (CS) and coconut shell ash (CSA) are unavoidable byproducts from agricultural industry. As a part of solid waste management, the investigation was carried out to evaluate the effect of replacing cement by CSA and coarse aggregate by CS.
Of Coconut Shell As Coarse Aggregate Replacement. 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 ratio124 .The results shows that 25 to 50 normal coarse aggregate replacement with coconut shell results gave 28Nmm2 and at 28day with water cement .
Coconut shells were obtained locally in Arena market Oshodi, Lagos state. Ordinary Portland cement available locally in Nigeria was used. Portable water in the Department of Civil Engineering, Federal polytechnic Ilaro was used. The coconut shells were dried in the sun for forty eight hours. It .
investigation to assess the suitability of sawdust and palm kernel shells as replacement for fine and coarse aggregate in the production of reinforced concrete slabs, [8] concluded that 25% sawdust and palm kernel substitution reduced the cost of concrete production by .
to replace the coarse aggregate in the concrete mix. The use of waste material as a substitute to replace the coarse aggregate in the concrete mix can be beneficial to humans. Coconut is one of the alternatives that can be used to replace the supply of coarse aggregate. Coconut is .
Coconut shell as replacement of coarse aggregate 17 Coconut shell as replacement of fine aggregate 18 Compressive strength machine 23 Splitting tensile strength Machine 24 Three point loading (ASTM C78) 25
Results show that replacement of appropriate coconut shell content able to produce workable concrete with satisfactory strength. Integration of coconut shell enhanced the strength of concrete making it to be the highest as compared to conventional concrete mixture.
