https://orcid.org/0000-0001-8570-0580
HighlightsPossibility of coconut coir for surface mortar reinforcement was investigated.Coconut coir in the mortar tends to slightly reduce bulk and dry density.Water absorption, porosity, sorptivity were increased with coconut coir fraction.The strength of mortar improved with additions of coconut coir up to 0.5% fraction.Presence of coconut coir improve post-crack behavior of mortar.
AbstractThis study was to investigate the effect of coconut coir on the strength and durability properties of cement-lime surface plaster mortar. The purpose of adding coconut coir into the mortar was due to coconut coir had a capacity in controlling cracking in the mortar. In this study, total 115 samples were prepared which were 100 cubes (150mm×150mm×150mm) and 15 beam prisms (100mm×100mm×500mm). Testing was included; water absorption, porosity, sorption rate for physical properties; acid attack resistance, alkaline attack resistance for durability properties; compression and flexural bending for strength properties. The samples were tested with mortar containing 0.125%, 0.25%, 0.50% and 0.75% of coconut coir. The percentage of coconut coir fraction was calculated based on the cement, lime, sand mix by mass. Test results show that, although compressive and flexural bending strength are not improving, but post crack properties such as ductility, residual strength, and toughness are increased with higher coconut coir fraction in the matrix.
