#0183;#32;Then the Water is added and the mix is continued. Production of mix (normal concrete of grade M 20) in the laboratory is carried out by IS method of concrete mix design (IS ). Coconut shell concrete is produced by adding coconut shells in different percentage ( 25% and 50%) replacement for coarse aggregate.
#0183;#32;AIMS OF THE PROJECTA determine various alternatives available for coarse aggregate. carryout a detail analysis on coconut shells as a coarse aggregate in concrete. prepare a methodology for the project amp; its analysis. enlist advantages amp; short comes of coconut shell as a coarse aggregate material. determine the strength of the concrete beam
Concrete made from coconut shell waste as coarse aggregate will be studied for compressive strength, tensile strength and flexural strength. the percentage replacement will be 0%, 10%, 20% and 30% with natural coarse aggregates and replacement of 10% various size of coconut shell in concrete. the replacement 10% of coconut shell and added coir fibre on high temperature.
Light weight aggregate concrete beam with coconut as aggregate is tested in bending (flexural) of capacity 23. TEST RESULTS Failure mode In the control concrete beam initial crack is 35 kN. The coconut shell 25% beam initial crack is 25 kN. The coconut shell 50% beam initial crack is 30 kN.
taken into consideration during the selection of the optimum coconut shell aggregate concrete mix. Also, the concrete mix was optimized for coconut shells cement ratio and w/c ratio. This optimum mix was then used throughout the entire investigation for the production of
coconut shell is more eco friendly than other materials. The author aimed to figure out confining strength of concrete By substituting coconut shell for natural coarse mix with replacement of 0, 1/4, 1/2, 1 parts . For each case they prepared 3 samples of M20 grade mixture in the shape of cubes and
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.
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 [8] for concrete of grade of M20. Based on the mix design, a mix ratio of 1: : with water to cement ratio of was adopted.
and 42% for concrete produced from coconut shell and palm kernel shell respectively [6,7]. Siti Amin Bt Tukiman and Sabarudin Bin Mohd (2009) replaced the coarse aggregate by coconut shell and grained palm kernel in their study. Percentage of replacement by coconut shell were 0%, 25%, 50%, 75% and respectively.
#0183;#32;Some studies have used broken coconut shell as a substitute for fine and coarse aggregate in hollow concrete blocks. In a study, researchers have used broken coconut shells and coconut fibre as a
This indicates that the coconut shell is a suitable composite and filler for enhancing the strength of conventional solid and hollow concrete. Moreover, filled coconut shell concrete building blocks are more load bearing. Average Split tensile strength for 7 days and

#0183;#32;Concrete prepared with 10% coconut shell aggregate replaced with coarse aggregate in mix design of M 25 and M 30, showing a pH value of 12 over the other concrete . Some defects arise in concrete after times are acid attacks, sulphate attacks, carbonation, corrosion and
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 [8] for concrete of grade of M20. Based on the mix design, a mix ratio of 1: : with water to cement ratio of was adopted.
Nowadays, the rising cost of building materials for construction purposes is a factor of great concern. The price of building materials is rising day by day. Now, most of the researchers are paying much attention on the suitable materials which can
Results revealed that with 40% replacement of conventional coarse aggregate by coconut shell, 7 days compressive strength of concrete decreased by %; whereas decrease in 28 days compressive strength was only %. 40% replacement makes the concrete lighter by %.

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.
The properties of concrete using crushed coconut shell as coarse aggregate were investigated in an experimental study. Coarse aggregate was replaced by crushed coconut shells in three different
