Coconut Shell (CS) are not commonly used in the construction industry but are often dumped as agricultural wastes. It was concluded that the CSs were more suitable as low strength-giving lightweight aggregate when used to replace common coarse aggregate in concrete production.
Based on the compression and splitting tensile strength of concrete, it can be established that the concrete containing 10% and 25% crushed coconut shell aggregates with the replacement of stone chips as coarse aggregates fulfills the requirements of the lightweight structural grade concrete.
Comparative Study on Coconut Shell Aggregate with Conventional Concrete Vishwas P. Kukarni, Sanjay kumar B. Gaikwad Abstract: Aggregates provide volume at low cost, comprising 66 percent to 78 percent of the concrete. Conventional coarse aggregate namely gravel and fine aggregate is sand in concrete will be used as control. While
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. The study
concrete mix design (IS 10262-1982). Coconut shell concrete is produced by adding coconut shells in different percentage (i.e. 25% and 50%) replacement in concrete. 3.3 Test on ingredients materials The ingredients of concrete i.e. cement, fine aggregate, fine aggregate, coconut shells are tested before producing concrete.
been investigated by various researchers , ,  and . In a study,  compared concrete made with coconut shells and palm kernel shells as replacement for coarse aggregates and concluded that coconut shells performed better than palm kernel shells as replacement for conventional aggregates in the of concrete. In an
Jan 22, 2016· 4. The 28 days compressive strength of coconut shell concrete was found to be 14.88 for 50% replacement by coconut shell aggregate under full water curing and it can be used for less important work. 5. Reduction in weight found to be 15% and 25% for replacement by coconut shell aggregate 25% and 50% respectively.
Oct 09, 2014· This indeed is an interesting question. I came across some research papers. I think, this particular review Paper has an answer to your question. Please read the conclusion from the paper given below. > * The possibility exists for the partial rep...
use lightweight concrete. The possibility exists for the partial replacement of coarse aggregate with coconut shell to produce lightweight concrete. Coconut shell exhibits more resistance against crushing, impact and abrasion, compared to crushed granite aggregate. Coconut shell can be grouped under lightweight aggregate.
Oct 01, 2011· The Behavior of Reinforced Concrete Beams with Coconut Shell as Coarse Aggregates CIVIL Project aims at analyzing flexural and compressive strength characteristics of concrete produced using crushed, granular coconut as substitutes for conventional coarse aggregate with partial replacement using M30 grade concrete. Beams are casted, tested and their physical and …

Increase in percentage replacement by coconut shell reduces compressive strength of concrete. Increase in percentage replacement by coconut shell increases workability of concrete. Coconut Shell can be used as partial replacement of coarse aggregate in R.C.C concrete. The following recommendations are made at the end of the study.
c. To investigate the feasibility of the combination of coconut shell as coarse aggregate in concrete by determining its compressive strength and durability. d. 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.
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 as a partial replacement of coarse aggregates. The effect of bond stress-slip behavior for
Use of coconut shell aggregate concrete as structural light weight concrete is recommended. Coconut shell aggregate is a potential construction material and simultaneously reduces the environmental problem of solid. Lightweight aggregate concrete (LWAC) is an important and versatile material in modern construction.
The coarse aggregates are the main ingredients of concrete. In this study, coconut shell is used as lightweight 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. Coconut shell exhibits more resistance against crushing compared to
It was advised that aggregate made from quartzite to be used for the concrete work. The study was made for the properties of concrete with coconut shells as the replacement of aggregate . The concrete with normal aggregate as well as coconut shell (CS) concrete with 10-20% coarse aggregate replacement with coconut shell were made.
Abstract: This paper presents the results of the investigation into the strength propertiesof concrete containing coconut shells as coarse aggregate replacement .
