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.
29/8/2017#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
concretes. Similarly Coconut shell being a hard and not easily degrade material if crushed to smaller size can be a potential material to partially substitute coarse aggregates in concrete. The concrete with ground coconut shell was found to be durable in terms of its resistance in water, acidic and alkaline surrounding.
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.
4. According to R. Nagalakshmi, M25 grade of concrete with cement replaced by fly ash and coarse aggregate by coconut shell and find its compressive, tensile strength. 5. According to Sabarudin Bin Mohd, he replaced coconut shell and palm kernel shell in place of coarse aggregate in concrete in 0,25,50,75 and 100 % replacement.
According to R. Nagalakshmi, M25 grade of concrete with cementreplaced by fly ash and coarse aggregate by coconut shell and find itscompressive, tensile strength. 5. According to Sabarudin Bin Mohd, he replaced coconut shell and palmkernel shell in place of coarse aggregate in concrete in 0,25,50,75 and100 % replacement.
Coconut shell as a completely substitution in the place of coarse aggregate may totally effective for designers in construction industry. The coconut shell concrete is a light weight solid which
Strength Properties of Coconut Shell as Coarse Aggregate In Concrete, being hard and of, The crushed granite aggregates were replaced as 25%, 5%, . Strength Properties of Concrete Containing, Strength Properties of Concrete Containing Coconut Shell as Coarse Aggregate, reduction in cost if coconut properly used shells are to replace se aggregate in .
5) In this study the use of coconut shell as coarse aggregate in concrete (5).the aim of project to that coconut shell aggregate is a construction material and reducing environment problem. The replaced coarse aggregate with 25%, 50%, 75% and of coarse aggregate. Test for workability, flexural,
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 %.
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. Conclusion is that the combinationof these materials has . potential of being used as. lightweight aggregate in co. ncrete and also has reduce the . material cost in construction [12].
Coarse aggregate was replaced by crushed coconut shells in three different percentages namely 25%, 50% and . Workability, compressive strength, flexural strength and splitting tensile strength
24/12/2016#0183;#32;Coarse aggregate was replaced by crushed coconut shells in three different percentages namely 25%, 50% and . Workability, compressive
21/2/2017#0183;#32;Coconut shells are more suitable as low strengthgiving lightweight aggregate when used to replace common coarse aggregate in concrete production. In the following paper the normal weight aggregate has been replaced by coconut shell aggregate and cubes have been casted to test their compressive strength and other physical properties.
It was found that with increasing proportion of coconut shells, there is decrement in compressive strength. 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.
In concrete mix the most important ingredient is the coarse aggregate therefore they used coconut shell as main ingredient and found better results . By collecti ng the test results they proved that using 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 .
7/7/2015#0183;#32;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.
Coconut Shell; Ewaste Partial Replacement Construction waste material; Plastic waste Partial Replacement Quarry dust For Partial Replacement Coconut Shell. The coconut shell can be used as a coarse aggregate in concrete. It has functional resistance capacity against crushing, impact amp; abrasion.
