| dc.description.abstract | The thesis "A Comparative Analysis of Concrete Compressive Strength with Coarse
Aggregate Replacement by Expanded Polystyrene Beads and Coconut Fiber Addition"
explores the use of EPS beads and coconut fibers as partial replacements for conventional
aggregates in concrete. The objective is to assess the effects of these eco-friendly materials
on compressive strength, particularly in lightweight concrete applications.
The study involves mixing different proportions of EPS beads (5%, 10%, 15%) and
coconut fibers into concrete and testing their performance after curing for 7, 14, and 28
days. The results show that incorporating 5-10% coconut fiber significantly enhances
compressive strength, while EPS beads reduce the overall weight of the concrete. However,
higher EPS content slightly affects workability.
This research demonstrates the potential of EPS and coconut fiber in producing
lightweight, strong, and sustainable concrete, suitable for applications like roofing and
flooring. It highlights the environmental benefits of using alternative materials in
construction, aligning with global sustainability trends. The work is done using M20 grade
concrete.
