coconut shells as coarse aggregate replacement. Furthermore, in this study, the effect of fly ash as cement replacement and aggregate replacement on properties of the coconut shells replaced concrete was also investigated. The concrete obtained using coconut shell aggregates satisfies the minimum requirements of concrete.
Water Absorption of Coconut shell =1% Slum required =50100mm Free moisture in sand =2% Preparation of Specimen Measurements of Ingredients: All cement, sand, coarse aggregate and coconut shell measured with digital balance. Water is measured measuring cylinder of capacity 1 lit and measuring jar of capacity 100 ml and 200 ml. ...
in the Coconut shell as long as it is not in a free form; it will not affect the setting and strength of concrete. It is found that ... Utilization of Coconut Shell as Coarse Aggregates in Mass Concrete" International Journal of Applied Engineering Research, ISSN Vol. 7 (2012). ...
Feb 05, 2019· APPLICATION OF COCONUT SHELL AS COARSE AGGREGATE Properties of coconut shell which may make it suitable coarse aggregate for concrete are i) it''s high strength and moduluspropertiesii)it''s high lignin content that makesthe composites more weather resistant iii) it''s low cellulose content due to which it absorbs less moisture as compared ...
Jun 01, 2017· 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 %.
An optimum percentage replacement of coarse aggregate with coconut shell aggregate is determined from the study. Coarse aggregate made from coconut shells were used in proportions of 5%, 10%, 15%, 20%, 25%, 30% and 35% to replace coarse aggregate in conventional concrete. A constant water to cement ratio of was used throughout the study.
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

Coconut Shell Aggregate The coconut shells are obtained from a local coconut field. They are sun dried before being crushed manually. Coconuts show a wide diversity in size, weight, shape and color, depending on genetic variety and maturity of the nut at harvest. The particle sizes of the coconut shell range from 5 to 20 mm.
Oct 13, 2018· Discarded fresh coconut shells were crushed mechanically and used as coarse aggregate with fly ash (FA) as partial replacement of Portland cement at 15% and 20% replacement levels by weight. Slump flow, T 500, Vfunnel, Lbox, and wet sieve segregation tests were used to evaluate the selfcompactibility of the developed mixes. For comparison ...
Coarse Aggregate Coconut Shell Ash Cement Cement is used right from ancient periods in construction industry. In the most general sense of the word, cement is a ... amounts of free CaO or MgO are present in the cement, these oxides can slowly hydrate and cause expansion of

This makes it a material of choice in construction. This research work reports the investigation carried out to determine the use of coconut shell as an aggregate in light weight concrete. Concrete samples were produced with different mix ratios, to determine the best and economic proportions that will give acceptable compressive strengths.
aggregate. Coconut shell can be grouped under lightweight aggregate. There is no need to treat the coconut shell before use as an aggregate except for water absorption. Coconut shell is compatible with the cement. The 28day airdry densities of coconut shell aggregate concrete are less than 2000 kg/m3 and these are
coarse aggregate with coconut shell aggregate is determined from the study. Coarse aggregate made from coconut shells were used in proportions of 5%, 10%, 15%, 20%, 25%, 30% and 35% to replace coarse aggregate in conventional concrete. A constant water to cement ratio of was used throughout the ...
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...
that agriculture waste coconut shell can also be used as coarse aggregate for concrete. 2. COCONUT SHELL Coconut is grown in more than 93 countries. India is the third largest, having cultivation on an area of about million hectares for coconut production. Annual production is about 7562 million nuts with an average of
USE OF COCONUT SHELL FROM AGRICULTURE WASTE AS FINE AGGREGATE IN ASPHALTIC CONCRETE ... studied the properties of concrete that using coconut shell as coarse aggregate and the result is the compressive ... aggregates. It shows that coconut shell has .
coconut shell aggregate was high about 24% but the crushing value and impact value was comparable to that of other lightweight aggregates. They found that the average fresh concrete density and 28day cube compressive strength of the concrete using coconut shell aggregate were 1975 kg/m3 and N/mm 2, respectively.
