and sand used in this study. Total powder content used for the self-compacting coconut shell concrete (SCCSC) was 510kg/m 3 while that of self-compacting conventional concrete (SCCC), which served as control, was 450kg/m 3. Water/powder ratio of 0.33 and the super plasticizers (SP) of 1.75% of total powder content were used throughout
river sand (50% of the mortar volume) as fine aggregate. Total powder content, SP dosage and w/b ratio were fixed at 510kg/m 3, 1.75% and 0.33 respectively.
1. Introduction. In ancient period, the structures were constructed by using materials like lime, clay, mud, surkhi, wood, egg, jaggery, sugar, burnt coconut shells etc. Oral traditional sources tell us egg whites were used as ingredients of mortar, which were used to bind building materials for the ancient constructions.
proportion of coconut shell powder (5, 10, 15, and 20) and clay. The test is carried out and the maximum unconfined compression strength is found for different proportions. among these tested samples had a better value in proportion in the mix of bottom ash 20% + coconut shell powder 15%,
2.2.2 Concrete Mix Proportions: Prescribed concrete 2.1.4 Coconut Shell Ash (CSA): The Coconut Shell Ash mix of 1:2:4 and water-cement ratio 0.55 was used to (CSA) was obtained by burning the coconut shell to a investigate the effect of CSA as admixture in concrete. temperature of 600–650ºC in an incinerator and Six mixes were used; ACM-00 ...
The ratio of mortar mix used here is 1:4. 53 grade ordinary portland cement is use in the project. The compressive strength, split tensile, flexural strength of specimen are found at 7 days and 28 days and compared with the normal mix to find the influence of foundry sand, GGBS and Silica fume in cement mortar.
Venus) and some shells are uni-Valved (Puritella). The shell we have used is washed to remove the chlorine ion which gets stick to it due to the constant contact of sea water. We have managed to grind the shell at a rice mill in Attayampatti and it is of the size of about 4.75mm and below. The colour of the shell after grinding is of dirty white.
ceramic waste powder as a substitute to cement and coconut shell as a substitute for conventional coarse aggregates. Finally, this project concludes that the compressive, Split tensile and flexural strength of concrete increases upto 10% replacement of cement with ceramic powder and coarse aggregate with coconut shells.
The average fresh concrete density and 28-day cube compressive strength of the concrete using coconut shell aggregate were 1975 kg/m 3 and 19.1 N/mm 2 …

In the mix proportioning, aside controlling aggregate quantities and low water/binder ratio, it is common to apply high range water reducing admixture to take care of flowability and a large quantity of powder materials to achieve high resistance to segregation [7].The concept of SCC was first proposed by Okamura in 1986, but it wasn't until ...
are going to partially replace coarse aggregate with coconut shell with myrobalan powder as admixture. Coconut is grown in more than 93 countries. South East Asia is regarded as the origin of coconut. India is the third largest, having cultivation on an area of about 1.78 million hectares.
The main objective is to identify the properties of coconut shell powder mortars. The experiment start with using 0%, 5%, 10% and 20% of CSP replace fine aggregate in mortar mixing. The proportion of sand to cement to water used in mortar mix design is 2.75: …
In this investigation, coconut shell was used for the production of high strength lightweight concrete. The dry density and cube compressive strengths were measured. Coconut shell aggregate ...
Coconut fiber is extracted from the outer shell of a Coconut. The common name, scientific name and ... mortar as compared to that of plain mortar for both mix design with all fiber contents. However, a ... 10% substitution of sand by the marble powder in the presence of a super plasticizing admixture provided maximum compressive strength at the ...
