Coconut Shell Powder were obtained from coconut shell that had been discarded and grinded until it become in a form of powder. This study were conducted to determine the chemical and physical properties of coconut shell powder to be used as a filler inside 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. Moisture retaining and water absorbing capacity of Coconut Shell are more compared to conventional aggregate.
agricultural waste. The concrete with ground coconut shell was found to be durable in terms of its resistance in water, acidic, alkaline and salty. Coconut shell being a hard and not easily degrade material if crushed to size of sand can be a po-tential material to substitute sand. At present, coconut shell

The coconut shell concrete was designed for characteristic strength of 30MPa with the incorporation of coconut shell as replacement for fine and coarse aggregate at 10%, 20% and 30% of volume fractions respectively. The workability, compressive strength as well as densities and water absorption of 96 cured
at different coconut shells (CS) replacements and study the transport properties of concrete with coconut shells as coarse aggregate replacement. Furthermore, in this study, the effect of fly ash as cement replacement and aggregate replacement on properties of the coconut shells replaced concrete was also investigated.
This study was conducted to investigate the properties of concrete using coconut shells as replacement for crushed granite and to assess the potential use of coconut shell concrete as a structural material as well as contribute to knowledge on the use of waste materials in construction in Ghana.
To check various properties of coconut shell concrete mix like - Density - Modulus of Elasticity - Workability - Water-cement ratio - Water absorption - Slump cone c. To investigate the feasibility of the combination of coconut shell as coarse aggregate in concrete …
1. Coconut shells are applicable as partial substitute as coarse aggregates for concrete roof tiles. 2. The good indicators of coconut shell quality as aggregate of concrete roof tiles are particles, shape and texture, resistance to crushing, absorption and surface moisture, and light-weight. 3.
concrete made with coconut shell and palm kernel shell as replacement of coarse aggregate and concluded that coconut shell performed better than palm kernel shell in concrete in terms of strength. Studies by [8also ] indicated some of the advantages of using coconut shell ascoarse aggregate replacement in concrete include high strength,
concrete using coconut shell as coarse aggregate were investigated in an experimental study and the study concluded lightweight concrete . From the research works reviewed above, it can be understand that coconut shells can be successfully used as a substitute for coarse aggregate in concrete. ...
Use of Coconut Shells in Concrete Prabhat Sharma1 Sooraj Jain2 1Resident Engineer 2Assistant Professor 1L. N. Malviya Infra Project Pvt. Ltd 2Laxmi Narian College of Technology Abstract—Concrete properties with coconut shells (CS) as partial replacement of aggregate were studied. Conventional
