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.
Coconut is an important crop for many populations around the world. It provides food, materials, and economic support. In the Philippines specifically, coconut is very important as 25% of cultivated land is planted with coconut and 33% of Filipinos depend on it for their livelihood. Several studies have explored partially replacing traditional concrete …

A single coconut palm may yield 100 coconuts annually, and each fruit requires a year to fully ripen. Mature coconuts, ovoid or ellipsoid in shape, 300–450 mm (12–18 inches) in length and 150–200 mm (6–8 inches) in diameter, have a thick fibrous husk surrounding the familiar single-seeded nut of commerce.A hard shell encloses the …
1. Introduction. Increased consumption of coconut water and green coconut fruit pulp has increased the generation of coconut shells (Ayrilmis et al., 2011), which in some regions tends to become waste, generating negative social, economic and environmental impacts (Biggs et al., 2015).Due to the lack of management and …
The study concurs with other researchers on the positive effect of torrefying biomass feedstock, particularly the coconut shells. It is concluded that torrefaction at …
The coconut industry generates a relatively large amount of coconut shell and husk biomass, which can be utilized for industrial and environmental purposes. Immense potential for added value when coconut shell and husk biomass are turned into biochar and limited studies are available, making this review paper significant.
