Abstract

The aim of this study is to determine the influence of coconut coir fiber on the compressive and flexural strength of paving blocks. The research was carried out using paving blocks with dimensions of 20cm×10cm×6cm, mixed with coir fiber by 0%, 0.1%, 0.2%, and 0.3% by weight. The results showed that no addition of coconut coir fiber resulted in compressive strength of 24.49Mpa, while the addition of 0.1% coconut coir fiber resulted in compressive strength of 25.39Mpa after 7 days. A mixture with no coconut coir fiber resulted in flexural strength of 31.5Mpa while the addition of 0.1% coconut coir fiber gave a flexural strength of 33Mpa in the age of 14 days. The conclusion of this study is that the addition of 0.1% coconut coir fiber in a paving block mixture can increase its compressive and flexural strength.

Highlights

Coconut fiber use in a reinforced concrete mixture to increase its strength is widely researched
From the result of paving blocks’ compressive strength at the age of 7 days (Figure 3) we can see that there is an increase from the addition of 0.1% coir fiber which was 259kg/cm2 (4% increase as compared with the normal paving block)
This is in accordance with the results reported in [18], namely that concrete mixed with coconut coir fiber will be lighter but in a certain amount will decrease its compressive strength

Summary

Introduction

Coconut fiber use in a reinforced concrete mixture to increase its strength is widely researched. We used coconut coir fiber for a mixture of paving blocks. Paving block pavements start to be widely used for pavement construction on roads [1]. This can be seen from the use of paving blocks which are increasingly used as asphalt replacement because they are easy to install, do not require heavy equipment, can be mass produced, and are easy to maintain and reinstalled. The contribution of this research is the utilization of coconut fiber as a substitute for steel to paving blocks, making it cheaper
