Abstract:
Coir pith is a coconut waste derived from the extraction of coconut fiber that accounts
for 70% of total husk.With an estimated 6.7 million husks produced in the Philippines
annually, a large fraction of waste known as coir pith is left to rot, thrown or burned.
Coir pith in cement board composite is applicable as insulation and a light indoor construction
material due to its high-water absorption properties and less strength. The
study sought to solve the high-water absorption problem while aiming at improving
the strength and durability of the composite that will meet the needs for indoor and
outdoor construction materials. According to the study’s findings, QUAC increases
the hydrophobicity of coir pith-cement composites, improves interfacial bonds, and
has the potential for light indoor and outdoor construction.
