This paper presents the findings of an investigation on the use of coconut shell ash (CSA) as admixture in concrete and its effect on durability performance. The CSA used was obtained by controlled burning of coconut shell in an incinerator to a temperature of 600–650ºC for 3 hours, air cooled, sieved through 75μm sieve and characterized by ...

Fig.1 Coconut Shell Fig.2 Waste Coconut Shell . 3 P ROPERTIES OF C OCONUT S HELL a) Coconut shell has high strength and modulus proper-ties. b) It has added advantage of the high lignin content. High lignin content makes the composites more weather resistant.

 · 2.70. This indicates that coconut shell is lighter than coarse aggregate and more volume of coconut shell will be required to replace equal weight of coarse aggregate in concrete. The bulk density of coconut shell obtained is 648 which far less thanis about 1437 of coarse aggregate implying its good for lightweight concrete.

 · 2.4.3 Carbonization of Coconut Shell Ash Coconut shells are cheap and readily available in high quantity. Coconut shell contains about 65 – 75% volatile matter and moisture which are removed largely during the carbonization process. The carbonization process involves converting the coconut shells to char (charcoal). The

 · Abstract and Figures Coconut fiber was used in coconut shell concrete (CSC) and its durability properties were studied. The properties …

The water absorbed by the coconut shell during the course of soaking is stored and the pore structure in the coconut shell behaves like a reservoir. Intermittent curing condition produces the highest coconut shell aggregate concrete strength followed by full water curing . Coconut shell concrete have a good quality in its later stage.

 · Therefore, this study examines durability performance of quarry dust as fine aggregate and coconut shell as coarse aggregate in concrete. Durability properties investigated include the absorption ...

 · Abstract. In this study hollow blocks were produced using coconut shell (CS) as coarse aggregate. For comparison, hollow blocks were also produced with conventional concrete (CC). Mixes were produced both in field and laboratory. Both conventional and CS mixes satisfied the minimum strength required as per IS 2185 (Part 1): 1987.

 · The surface texture of the coconut shell is fairly smooth on concave and rough on convex faces. CS aggregates have a relatively high water absorption value nearly 6.71%, compared to the conventional fine aggregate (3%). The physical properties of Coconut shell are shown in Table 1. Table 1: Physical Properties of Coconut Shell

The effective use of silica fumes for the improvement of strength of lightweight coconut shell concrete. The Maximum compressive strength at 28 days when 15% silica fumes& 15% coconut shell is added to the mix and the value obtained is 34.04MPa.

This study used experimental design to determine the effectiveness of adding crushed coconut shell as additives in concrete mixture. The t-test analysis revealed that the flexural and compressive strength of concrete with crushed coconut shell was significantly higher than the flexural and compressive strength of concrete without crushed ...

 · Therefore, this study examined the effect of coconut shell as fine and coarse aggregate replacement in concrete with respect to the mechanical properties. The coconut shell concrete was designed for the characteristic strength of 30 MPa with the incorporation of coconut shell as a replacement for fine and coarse aggregate at 10%, 20% and 30% …

 · Coconut fiber was used in coconut shell concrete (CSC) and its durability properties were studied. The properties include: water absorption, volume of permeable pore voids, rapid chloride penetration test, sorptivity and resistance at elevated temperature. For comparison purpose, these properties were also studied on conventional concrete (CC) …

 · In a quest to improve the sustainability of concrete mixtures, this study was carried out to investigate experimentally and statistically the performance of concrete made with coconut shell ash as partial replacement of Portland cement (PC).
