(6 beams with coconut shell concrete and 6 beams with conventional concrete) with varying reinforcement ratio( % to %) were fabrication and tested. Data presented include the deflection characteristics, cracking behavior, mid span deflection and
study is the combination of coconut shell and grained palm kernel shell has potential as lightweight aggregate in concrete. Also, using the combination of coconut shell and grained palm kernel as aggregate in concrete can reduce the material cost in construction because of the low cost and abundant agricultural waste.
lightweight concrete has density of 1440 kg/ m 3 to 1840 kg/m 3 compared to normal weight concrete with a density in the range of 2240 kg/ m 3 to 2400 kg/ m 3. For structural application, the concrete strength should be greater than MPa. Table show the Classification of Lightweight Concrete.
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. Keywords: coconut shell, concrete, coarse aggregate, compressive strength, split te nsile strength, flexural strength.
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 lightweight. 3.
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. Keywords: coconut shell, concrete, coarse aggregate, compressive strength, split te nsile strength, flexural strength.
Structural LWC has an inplace density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³) compared to normal weight concrete a density in the range of 140 to 150 lb/ft³ (2240 to 2400 kg/m³). For structural applications the concrete strength should be greater than 2500 psi ( MPa).
The coconut shell is light weight aggregate and more suitable for construction because toughness of coconut shell is high and which is easily available. II Objective: 1. To find economical materials for high cost construction. 2. To prepare lightweight concrete structure by .
The water/cement ratio [w/cm] is in the range from to and a of microscopic bubbles with at least a majority being in the range from 25 µm to 100 µm [ to mm / inches to inches] in diameter. * Normal cellular concrete bubble range is mm mm [ in.

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.
concrete[4]. Coconut shell is categorized as light weight aggregate. The coconut shell when dried contains cellulose, lignin, pentosans and ash in varying percentage [5]. In Asia, the construction industry is yet to realize the advantages of light weight concrete in high rise buildings [6]. Coconut
Keywords: concrete, coconut shells, compressive strength, coconut shell concrete I. INTRODUCTION Coconut shell is used as light weight aggregate in concrete. Coconut shells are byproducts of coconut oil production. Coconut shells are used in the production of activated carbon due to .
(uncontrolled combustion) for three hours to produce coconut shell ash (CSA), which in turn was used as pozzolana in partial replacement of cement in concrete production. Concrete cubes were produced using various replacement levels of 0, 10, 15, 20, 25 and 30 percent of OPC with CSA. A total of 54

Jun 20, 2018· Bond strength is responsible for the transfer of forces between the two materials ensuring strain compatibility and composite action. In this study, the bond strength property of reinforced coconut shell aggregate concrete was investigated by pullout test. The pullout test was carried out on concentrically reinforced concrete cubes.
by coconut shells can be used in producing lightweight concrete. % replacement of crushed granite with coconut shells can be used to produce structural concrete per the requirements of [10].
