Being a substitute it can reduce the aggregate quantity and provide good aesthetic appearance. It can be a good choice for reinforcing concrete structure located close to the sea such as bridges and houses. Concrete being weak in tension, coconut shells can be used in the tension zones of the slabs. Coconut shell being a light
Coconut shell exhibits more resistance against crushing, impact and abrasion, compared to crushed granite aggregate. Coconut shell can be grouped under lightweight aggregate. 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.

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  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 shell as substitute for either fine or coarse aggregate in concrete production. (Olanipekun et al., 2006) Investigated the comparative cost analysis and strength characteristics of concrete produced using crushed, granular coconut and Palm kernel shell as substitutes for conventional coarse aggregate. It was concluded that the coconut shell
Jun 01, 2017· They found that there was adequate bonding between the coconut shell aggregate concrete and the steel bars. Ganiron used coconut shells and fiber as substitute for aggregates in developing concrete hollow block. The study was carried out for various percentage of coconut shell content as partial replacement of conventional aggregate.
Properties of Concrete with Coconut Shells as Aggregate Replacement 22 2.2. Mix proportions In order to investigate properties of CS concretes, six mixes were employed. Control mix (M1) that is, without CS was made. Coarse aggregate was then replaced with CS in 10 (M2), 15 (M3), 20 (M4) percentages to study effect of CS replacement.
The results also indicated cost reduction of 30% and 42% for concrete produced from coconut shells and palm kernel shells, respectively. Considering the strength/economy 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 ...

reinforced coconut shell aggregate concrete beams were studied by making prototype elements and the results are compared with the other LWA used in concrete. Comparisons of some properties for coconut shell aggregate concrete were made using some codes of practice and other LWC. Also,
strength to mortars and concretes. Similarly Coconut shell being a hard and not easily degrade material if crushed to smaller size can be a potential material to partially substitute coarse aggregates in concrete. The concrete with ground coconut shell was found to be durable in terms of its resistance in water, acidic and alkaline surrounding. 2.
