| dc.description.abstract | Expanded polystyrene (EPS) beads are lightweight aggregates that can be used to
produce lightweight concrete. Coconut fiber is a natural fiber that can be used as
reinforcement in concrete. This study investigated the compressive strength of
lightweight concrete made with different percentages of EPS beads and coconut fiber. In
this thesis project, we used 0% EPS beads, 5% EPS beads and 10% EPS beads
respectively. EPS and coconut fiber were used as partial aggregate replacements for
volume in the mixes. Cylinders of 4 to 8 inches in size were prepared in this study. These
include full water curing, air-dry curing, 7-day curing, and 28-day curing. The water
absorption of a cylinder with EPS beads and coconut fiber is 0%, 5%, and 10% EPS
beads and coconut fiber, respectively. 7 days for EPS, it was found that in the 0%, 5%,
and 10% EPS beads. It was found after 28 days for EPS beads that in the 0%, 5%, and
10% EPS beads. It was discovered after 7 days that the 0%, 5%, and 10% coconut fiber.
It was found after 28 days for coconut fiber that in the 0%, 5%, and 10% coconut fiber.
The results showed that the compressive strength of the concrete increased with the
addition of EPS beads and coconut fiber. The optimum percentage of EPS beads and
coconut fiber for maximum compressive strength. The study also investigated the effects
of EPS beads and coconut fiber on the workability and flexural strength of the concrete.
The results showed that the workability of the concrete decreased with the addition of
EPS beads and coconut fiber. However, the flexural strength of the concrete increased
with the addition of EPS beads and coconut fiber. The results of this study suggest that
EPS beads and coconut fiber can be used to produce lightweight concrete with high
compressive and flexural strength. This type of concrete can be used in a variety of
applications, such as roofing, flooring, and wall panels.
