This study
investigates the impact of meshed coconut coir on the mechanical and durability
properties of coir-reinforced cement concrete, aiming to control internal and
external cracks. The meshed form of coir is known for its ability to mitigate
shrinkage, enhancing both strength and durability. Phase I of the experimental
investigation involved preparing 49 samples: 28 cubes (150x150x150mm) and 21
beam prisms (100x100x500mm). The tests included water absorption, porosity,
sorption rate for physical properties, acid and alkaline attack resistance for
durability, and compression and flexural bending strength for mechanical
properties. The coir was tested in treated and untreated forms, with single and
double layers in the concrete. Results indicated that while compressive and
flexural bending strengths showed modest improvements, post-crack properties
such as ductility, residual strength, and toughness significantly increased
with higher fractions of meshed coir. Meshed coir reinforcement, used in
layers, is proportioned between 5% to 25%. This natural fiber enhances material
strength and durability, offering an eco-friendly alternative for construction
and manufacturing applications. Its usage improves structural integrity while
promoting sustainability. The findings suggest that meshed coconut coir can be
a valuable addition to concrete, providing better crack control and improving
post-crack behavior.
