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 investigation to assess the suitability of sawdust and palm kernel shells as replacement for fine and coarse
Coconut sh ell (CS) is one of the agricultural waste and made customary in the manufacturing of coconut shell aggregate concrete (CSAC) by researcher almost one decade too . Most of the research results on coconut shell used concrete were encouraged to use it in the field applications concrete as well.
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. ...
aggregate. To opt for green construction, use of coconut shell as coarse aggregates is a right choice, since coconut shell aims to produce light weight concrete and would definitely help in increasing the speed of construction. Till now, only the study regarding coconut shell as aggregate in .
Coconut shell as coarse aggregate The coconut shells were obtained from a local coconut field located in Kampung Kurnia Kuantan Pahang. They were sun dried for 1 month before being crushed manually. The crushed materials were later transported to the laboratory where they were washed and allowed to dry under ambient temperature for another 1 month.
Abstract: The effect of coconut shell and its ash has been investigated and the experiments have been done to utilize these waste materials with concrete as a partial replacement for coarse aggregate and cement. The coconut shell in the form of aggregate is a material which can be a substitute for coarse aggregate in concrete.
For coconut shell aggregate to be used efficiently for construction purposes, it is imperative to investigateitsproperties. Therefore, this study examined the effect of coconut shell as fine and coarse aggregate replacement on the behavior of concrete with respect to some vital properties. The coconut shell concrete was designed for
coconut shell concrete with the replacement of 16%, % and 20% by coarse aggregate By testing the concrete cubes, at th28 day 16% replacement of coarse aggregate by coconut shell shows that the strength of the coconut shell concrete was decreased by % from control mix. Similarly for .
The coconut shells were crushed using hammers to a size such that it passes through a mm sieve and retained on 10mm sieve. The material was used to partially replace coarse aggregate with coconut shells. SCC mixes were prepared by replacing natural coarse aggregate with %, 5% and 10% of Crushed Coconut Shell (CCS) by weight.
Sep 15, 2017· Abstract. An experimental investigation was carried out to study the durability properties of Coconut Shell (CS) aggregate concrete. Effect of mineral admixtures such as fly ash and ground granulated blast furnace slag (GGBFS) as partial replacement of cement on durability properties of CS aggregate concrete was also verified.
Comparative Study On Coconut Shell Aggregate Concrete. Coconut shell can be used as partial replacement of coarse aggregate in rcc concrete permeable voids and water absorption increases with increase in cs replacement using the combination of coconut shell as aggregate in concrete can reduce the. morethere will
of coconut shell as coarse aggregate in concrete by determining its compressive strength and durability. c. 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 and also the mechanical properties mentioned above.
• Coarse aggregate • Fine aggregate • Mineral filler – stone dust and Coconut shell charcoal. • Binder – bitumen of penetration grade 60/70 • Stabilizer – Cellulose fibre (% %) Materials details. Coarse aggregate: The coarse aggregate should be crushed rocks which should pass through 19mm sieve and retained
agriculture waste coconut shell can also use as coarse aggregate for concrete. Coconut Shell Coconuts are referred to as "man's most useful trees", "king of the tropical flora" and "tree of life". Coconuts or its scientific name "cocosnucifera" are the most important of cultivated palms and the most widely distributed of all palms.
: Coconut shell concrete. 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.
Testing of properties of cement, fine aggregate, coarse aggregate and coconut shells. Production of concrete mixes Production of mix (normal concrete of grade M20) in the laboratory is carried out by IS method of concrete mix design (IS ). Coconut shell concrete is produced by adding coconut shells in different percentage
