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
2.2 COCONUT SHELL AS COARSE AGGREGATE:-Coconut shell is used as light weight aggregate in concrete. Coconut shells are by-products of coconut oil production. Coconut shells are used in the production of activated carbon due to hardness and high carbon content. Various researchers have investigated the use of coconut shells and
the compressive, tensile and flexural behavior of concrete 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.

studied the properties of concrete that using coconut shell as coarse aggregate and the result is the compressive strength is decrease as the percentage of coconut shell increase. Coconut shells also have been used since long ago to build the house . Besides, coconut shells also
Abstract. In this study, coconut shell was used as recycled lightweight aggregate in concrete. For coconut shell aggregate concrete (CSAC) to be used in realistic situations, its strength, durability and its temperature resistance need to be examined.
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.
behaviour of reinforced concrete beams with coconut shell as coarse aggregates 1. behaviour of reinforced concrete beams with coconut shell as coarse aggregates [light weight aggregate] eswari by …
Concrete obtained using coconut shell as a coarse aggregate satisfies the minimum requirements of concrete. Coconut shell aggregate resulted acceptable strength which is required for structural concrete. Coconut shell may present itself as a potential material in the field of construction industries.
concrete. Also, using the coconut shell as aggregate in concrete can reduce the material cost in construction because of the low cost and abundant agricultural waste. Coconut Shell Concrete can be used in rural areas and places where coconut is abundant and may also be used where the conventional aggregates are costly.
Coconut shells replaced concrete. Key words: Strength, Coconut Shells, Concrete, Environment, Sustainability I. INTRODUCTION Framework improvement over the world made interest for development materials. Cement is the chief structural ... Use of Coconut Shells in Concrete ...
of coconut shell aggregate concrete are less than 2000 kg/m3 and these are within the range of structural lightweight concrete. Coconut shell aggregate concrete satisfies the requirements of ASTM C 330. 4. Conclusıon To increase the speed of construction, enhance green construction environment we …
coconut husk, corn cob, peanut shell etc have been identified as supplementary cementing materials in many parts of the world. ... series of concrete using fly ash surpass the strength of palm oil fuel ash concrete.
and the Philippines . Limited research has been conducted on mechanical properties of concrete with coconut shells as aggregate replacement [11,12]. However, further research is needed for better understanding of the behaviour of coconut shells as aggregate in concrete.
To investigate the effect of the combination of coconut shell as coarse aggregate in concrete content and length to the workability as lightweight aggregate in concrete. e.
converting the coconut shells to char (charcoal). The charring process (making of charcoal) is known as the Pyrolysis, which is chemical decomposition of the shell by heating in the absence of oxygen. During the carbonization of coconut shells, volatiles amounting to 70% of the mass of coconut shells on dry weight basis are released to the
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,
coconut shell used as a light weight aggregate in concrete, the properties of coconut shell concrete examined, Control concrete with normal aggregate and CS concrete with 10 - 30% coarse aggregate replacement with CS were made, and Constant water to cementitious ratio of …
industries are highly desirable. One such alternative is coconut shell (CS), which is a form of agricultural solid waste. This aggregate is abundantly available in countries like Indonesia, Philippines and India. The main coconut producers in the global market for 2010 are shown in Table 1. Lightweight aggregate concrete (LWAC)
coconut shells and fibers as an aggregate. Analyze the performance and the effectiveness of the coconut shells and fibers as aggregates in concrete hollow blocks in terms of physical properties like color, texture, size, and density and by mechanical properties like compressive strength, modulus
