| 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, 3% EPS
beads, 6% EPS beads and 8% 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%, 3%, 6%, and 8%. EPS beads
and coconut fiber, respectively. 7 days for EPS, it was found that in the 0%, 3%, 6% and 8% EPS
beads. It was found after 28 days for EPS beads that in the 0%, 3%, 6% and 8% EPS beads. It was
discovered after 7 days that the 0%, 3%, 6% and 8% coconut fiber. It was found after 28 days for
coconut fiber that in the 0%, 3%, 6% and 8% 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.
