Manufacture and Characterization of Light Bricks by Utilizing Coconut Fiber as an Aggregate for Soundproof Material

Introduction

The increasing demand for sustainable and environmentally friendly construction materials has led to the development of innovative building materials. One such innovation is the use of coconut fiber as an aggregate in making lightweight bricks. Coconut fiber is a by-product of the coconut industry, which is abundant in many tropical countries. Its use as an aggregate in brick production offers several benefits, including reduced weight, improved sound absorption, and sustainability. In this study, we aim to investigate the manufacture and characterization of light bricks using coconut fiber as an aggregate for soundproof material.

Background

Lightweight bricks have become an attractive topic of study in recent years, especially with the increasing demand for sustainable and environmentally friendly construction materials. The use of coconut fiber as an aggregate in brick production is one such innovation that has gained attention in recent years. Coconut fiber is a natural, biodegradable, and renewable resource that can be used as a substitute for traditional aggregates such as sand and gravel. Its use in brick production offers several benefits, including reduced weight, improved sound absorption, and sustainability.

Materials and Methods

In this study, we used a mixture of coconut fiber and sand as the aggregate in making lightweight bricks. The composition of coconut fiber varied from 0% to 5%, while the composition of sand ranged from 100% to 95%. The mixture used 200 grams of cement with a ratio of cement and aggregate of 1:4. The bricks were then subjected to physical and mechanical testing to evaluate their properties.

Physical Testing Results

Physical test results show that with the increasing number of use of coconut fiber as an aggregate, the brick density has decreased. This is caused by the light properties of the coconut coir itself, which can replace most of the weight of the sand. However, this decrease in density was followed by an increase in water absorption capability. That is, bricks that use more coconut coir tend to be more shaft and can absorb more water. This phenomenon is important to consider, especially in the use of bricks in areas that have high rainfall.

Mechanical Testing and Sound Absorption

In mechanical testing, the addition of coconut fiber has an impact on a decrease in compressive strength, impact strength, and brick hardness. Although this decline might worry for building quality, keep in mind that this lighter brick can still be used for applications that require construction materials that are not too heavy. On the other hand, the increase in the composition of coconut fiber actually increases the absorption of brick sounds. With a frequency limit of 1000 Hz, this brick shows a good ability to reduce sound, making it ideal for use in buildings that require acoustic isolation.

Characterization of Light Bricks

The characterization of light bricks using coconut fiber as an aggregate was evaluated based on their physical and mechanical properties. The results show that the addition of coconut fiber has a significant impact on the density, water absorption, compressive strength, impact strength, and brick hardness of the bricks. However, the increase in the composition of coconut fiber also increases the sound absorption of the bricks.

Conclusion

The use of coconut fiber as an additional aggregate in making light bricks brings various benefits, especially in aspects of sustainability and reduction of weight. However, it is important to consider trade-offs that occur, such as decreased compressive strength and violence. This brick offers an interesting alternative for environmentally friendly construction, especially in areas that require good sound control. With further research, a solution may be found to improve the mechanical properties of this mild brick while maintaining the benefits obtained from the use of coconut fiber.
