granite 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 28-day air-dry densities of coconut shell aggregate concrete are less than 2000 kg/m3 and these are within the

· 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 0.5 was used throughout the study.

Coconut shells can be used as coarse aggregate in concrete. It has functional resistance capability against abrasion, impact, and crushing. When used as coarse aggregate in concrete, no special treatment of coconut shell is required. Coconut husks are easily crushed into grains and transportation of this material is very economical.

The experiments carried out on all the materials used for the research work according to BS 4550 and BS 812 is as follows: 1. Cement a. Standard consistency test

for coarse aggregate. The use of plastic, paper and pulp industry waste, textile waste, rice ash, recycled rubber tyres, broken bricks are some examples for replacing aggregate in concrete. Coconut shell is an agricultural by product which can be used as coarse aggregate in concrete. According to report made in

Normal aggregate, that is, crushed blue granite of maximum size 20 mm was used as coarse aggregate. Well graded river sand passing through 4.75 mm was used as fine aggregate. The specific gravities of coarse and fine aggregates were 2.65 and 2.63 respectively. Coconut shells which were already broken into two pieces were

Test results and performance of coconut shell aggregate concrete pipes encourage the use of coconut shell as an aggregate for the replacement of conventional coarse aggregate in reinforced ...

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 0.5 was used throughout the study.

the coconut shell is produced about 3.18 million tonnes [6]. In this study the coarse aggregate is replaced by coconut shell in M15, M20, and M25 grades of concrete of 16%, 18.5%, and 20% each and compressive strength have been found out. From the results it have been concluded that coconut shell can be used as structural concrete and it leads

ABSTRACT. 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. Coconut shell aggregate exhibits low impact ...

profitability of coconut shells as a coarse aggregate as a contrasting option to characteristic aggregate in cement. 1. This trail work was held to acquire the quality of halfway supplanting of concrete with fly ash and smashed stone with coconut shells. 2. In this test two sources of substitution materials

To overcome this problem, coconut shell is used as a partial replacement of the coarse aggregate. For the replacement of this material, different tests on material was performed and mix design is ...

Coconut shell (CS) is used as aggregate in concrete. Now-a-days there is large use of aggregate is increasing day by day so rather than using coarse aggregate in concrete, natural material coconut shell shall be used for some construction. Coconut shell is a waste material from coconut and it is quite strong like aggregate.

The waste coconut shell may be utilized to replace natural coarse aggregate. In present study, compressive strength of concrete of M - 20 grades has studied by replacing natural coarse aggregates at 0%, 5%, 10%, 20% and 30%, by weight with coconut shell. Compressive strength of coconut shell concrete has been evaluated on 7, 14, 21 and 28 days.

Results revealed that with 40% replacement of conventional coarse aggregate by coconut shell, 7 days compressive strength of concrete decreased by 62.6%; whereas decrease in 28 days compressive strength was only 21.5%. 40% replacement makes the concrete lighter by 7.47%. Further, it was revealed that for mix design of concrete of 20 N/mm 2 ...

Concrete samples were produced with different mix ratios, to determine the best and economic proportions that will give acceptable compressive strengths. Concrete specimen were produced with coconut shell as coarse aggregate, ordinary river sand as fine aggregate and ordinary Portland cement as binders.

The coconut shell shows promising potential to be used as coarse aggregate, especially when it involves the costly replacement areas of conventional coarse aggregates. It has high toughness, durability, and abrasion resistance properties (Pappu et al . 2007; Nadir and Sijatha 2017).

The use of coconut shell as coarse aggregate in concrete has never been a usual practice among the average citizens, particularly in areas where light weight concrete is required for non-load bearing walls, non-structural floors, and strip footings. Although . 37 .

coarse aggregate in solving part of natural aggregate. The various waste materials are used such as coconut shell, cockle shell, periwinkle shell, foundry sand etc. so here in my project I will use coconut shell waste as replacement of coarse aggregate by different percentage for …

The budding of waste coconut shell are used as a alternative for coarse aggregate in concrete. After the coconut is tattered out, the shell is regularly discharged. The bulk density of coconut shell is about 500 to 600 kg/m3, producing concrete of about less than 2000 kg/m3 in density, which makes them
