Jan 22, 2016· 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 made lightweight concrete making use of .
examples of replacing aggregates in concrete. Coconut shell is categorized as light weight aggregate. The coconut shell when dried contains cellulose, lignin, pentosans and ash in varying percentage. In Asia, the construction industry is yet to realize the advantages of light weight concrete in high rise buildings.
Concrete cylinder specimens incorporating different percentage replacement of coarse aggregates using coconut shells with rebar were constructed and performed pullout testing to evaluate the bond behavior of concrete containing natural stone chips and crushed coconut shells .
No, crushed coconut shell cannot be used in concrete as fine aggregates for reasons of bond required for interlocking of the various materials used which will impart strength. However, it can be provided as a filler material in the concrete to make up the volume of concrete that will be necessary at usage site.

partially replaced by coconut shell in concrete by this agriculture waste material get reduced and minimize environment problems. II. Materials Cement Cement is a binder, a substance that sets and hardens independently, and can bind other materials together.
Jun 26, 2014· 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 lightweight.
In this study, coconut shell is used as light weight aggregate in concrete. The properties of coconut shell and coconut shell aggregate concrete is examined and the use of coconut shell aggregate in construction is tested. Moisture content and water absorption were .
To check various properties of coconut shell concrete mix like Density Modulus of Elasticity Workability Watercement ratio Water absorption Slump cone c. To investigate the feasibility of the combination of coconut shell as coarse aggregate in concrete by .
Aug 29, 2017· REINFORCED CONCRETE WITH COCONUT SHELL AS COARSE AGGREGATES. 9. LOAD CARRYING CAPACITY • The strength beam without coconut shell is 90 kN with a central deflection of 680 mm. • The strength beam with coconut shell 25% is 90 kN with a central deflection of 745 mm. • The strength beam with coconut shell 50% is 90 kN...
Coconut shells can be used as full replacement of crushed granite or other conventional aggregates in concrete construction. There is no need to treat the coconut shell before use as an aggregate except for water absorption.
Concrete being weak in tension, coconut shells can be used in the tension zones of the slabs. Coconut shell being a light weight material, usage of it in concrete can make the structure light weight. building blocks can be used where there is less load application.
Sep 15, 2017· An experimental investigation was carried out to study the durability properties of Coconut Shell (CS) aggregate concrete. Effect of mineral admixtures such as fly ash and ground granulated blast furnace slag (GGBFS) as partial replacement of cement on durability properties of CS aggregate concrete was also verified.
Dec 24, 2016· Periwinkle shell was chosen as a substitute for coarse aggregate in concrete [1] and palm kernel shell was used as a replacement for fine aggregate in concrete by some researchers [2].
Jun 06, 2017· Properties of coconut shell (CS) as an aggregate was studied with PPC cement. Control concrete with normal gravel aggregate and CS aggregate concrete at different percentage replacement were made and tested for various properties such as workability, compressive strength, flexural strength, split tensile strength and durability.
Coconut shell powder in varying percentages of1%, 3% and 5% was used as filler material in concrete grade 30 and evaluated after a curing period of 7 days and 28days respectively. Compressive strength, water absorption and carbonation tests were conducted to evaluate the strength and durability of CSP concrete in comparison with normal concrete.
Using same mix design, coconut shell concrete was prepared by replacement of conventional crushed coarse aggregate (CA) with waste coconut shell (CS). Coconut shell replaced conventional aggregate by 10%, 20%, 30% and 40% respectively (by volume) and the effect on compressive strength and density of concrete was observed.
