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.
limits for light weight aggregate hence requiring no need for treatment of the coconut shell before use as an aggregate. In addition, better workability is achieved because of the smooth surface of coconut shell aggregate on the concave face of the shells [6]. As part of efforts to make efficient use

The CSC with 50% coarse aggregate replacement using coconut shell aggregates had an average weight of 2095 kg/m 3, which was close to the density of lightweight concrete. The decrease in self-weight was due to the density of coconut shell aggregates, which was 550 kg/m 3 compared to the conventional aggregates with 1162 kg/m 3 (Sabih et al. 2016).
A coarse aggregate (CS) with a nominal size of 12.5 mm, crushed in a crusher machine with a fineness modulus of 6.1 and a specific gravity of 1.15, was used to prepare the lightweight geopolymer coconut shell concrete (GPCSC).
way of utilizing crushed coconut shell aggregate in concrete is presented in this paper. As coconut shell is available at a low price in most of the tropical countries. The concrete obtained using coconut shell aggregates satisfy the minimum requirements of lightweight concrete. Hence it is possible to
the direction of waste management strategies includes structural performance of concrete using periwinkle shell as light weight aggregate. Civil engineering practice and construction works in Nigeria depend on a very large extent on concrete. Concrete is one of the major building materials that can be delivered to a project site.

Lightweight Concrete Using Coconut Shells as Aggregate 453 granite aggregates are shown in Table 1. The sieve analysis of the river sand, CS aggregate and granite aggregates are illustrated in Fig. 3.
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 ...
Apeksha and Jain (2017) found that substitution of traditional aggregate by waste coconut shell (CS) delivered light weight concrete. About 22% decrease was accomplished in terms of density. It was likewise presumed that for each 10% supplanting with CS requires 3.6% of extra concrete substance.
Hence the use of coconut shells up to 40% can be encouraged for field applications that help in p rotecting the environment, as well as producing the light weight concrete.

The use of waste materials is one of the options for sustainable construction. In this paper the coconut shell waste is considered as coarse aggregate (after the same has been crushed) for preparing light weight concrete. The natural material like bamboo which is having considerable tensile strength is considered for reinforcement along with coconut shell concrete.
