A Comparative Study On The Compressive Strength Of Concrete Using Coconut Fiber And EPS Beads

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. Compressive strength, Expanded Polystyrene Beads, Coconut Fiber, Universal Testing Machine
