Effect Of Particle Size And Cement Composition Particle On The Quality Of Cement Boards From The Candlenut Shell (aleurites Moluccana Wild)
Introduction
The utilization of waste materials as raw materials for cement boards has gained significant attention in recent years. One such material is the candlenut shell (Aleurites Moluccana Wild), which has been explored as a potential substitute for traditional cement board materials. This study aims to investigate the effect of particle size and cement composition on the quality of cement boards produced from the candlenut shell. The findings of this research will provide valuable insights into the optimization of particle size and cement composition to produce high-quality cement boards.
Background
Cement boards are widely used in construction applications due to their durability, fire resistance, and ease of installation. However, the production of traditional cement boards requires significant amounts of energy and resources, contributing to environmental degradation. The use of waste materials, such as the candlenut shell, as raw materials for cement boards offers a promising solution to reduce waste disposal costs and promote sustainable development.
Methodology
This study employed a factorial design to investigate the effect of particle size and cement composition on the quality of cement boards. The candlenut shell was crushed into two different particle sizes: 30 mesh and 80 mesh. The cement composition was varied in the ratio of 80:20, 70:30, and 60:40. Magnesium chloride was added as a catalyst to accelerate the hardening process. The resulting cement boards were measured for density, water content, swelling of the thickness, water absorption, Modulus Elasticity (MOE), and flexural power (MOR).
Results
The results of this study showed that the density value of the cement boards ranged from 1.00-1.08 g/cm³, water content from 7.45-11.56%, swelling of the thickness from 5.28-7.02%, water absorption from 6.12-7.70%, MOE from 4.34-7.90 N/mm², and MOR from 5176-9158 N/mm². The density, water content, swelling of the thickness, and water absorption values met the JIS A 5417-1992 standards. However, the MOE and MOR values did not meet the standard, indicating that further research is needed to improve the mechanical strength of the cement boards.
Deeper Analysis
Particle Size
The size of the candlenut shell particle appears to have a significant effect on the quality of the cement board. The smooth particles (80 mesh) produced cement boards with better density, water content, swelling of the thickness, and water absorption. However, the mechanical strength was still not optimal.
Cement Composition
The variation of cement composition also affected the nature of the cement boards. The addition of a higher proportion of hazelnut shells (80:20) tended to produce cement boards with lower density, water content, and water absorption.
Magnesium Chloride Catalyst
The addition of magnesium chloride accelerated the hardening process, but its effect on the mechanical properties of the cement boards needs further investigation.
The Importance of Further Research
To produce high-quality cement boards, further research is needed to:
Optimization of Particle Size
Finding the ideal candlenut shell particle size to achieve optimal mechanical strength.
Addition of Additives
Examining the addition of additives such as natural fibers or polymers to increase the mechanical strength of the cement board.
Making Process
Developing the process of making cement boards that are more efficient and environmentally friendly.
Conclusion
The utilization of candlenut shells as raw material for cement boards is a positive step in supporting the concept of sustainable development. This research provides valuable insights into the optimization of particle size and cement composition to produce high-quality cement boards. Further research is needed to improve the mechanical strength of the cement boards and develop a more efficient and environmentally friendly making process.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Further research should focus on optimizing the particle size of the candlenut shell to achieve optimal mechanical strength.
- The addition of additives such as natural fibers or polymers should be examined to increase the mechanical strength of the cement board.

Future Directions
This research provides a foundation for the development of cement boards based on agricultural waste that is environmentally friendly and has a high economic value. Future research should focus on scaling up the production process and exploring the potential applications of cement boards in various industries.
Limitations
This study has several limitations that should be addressed in future research. The particle size of the candlenut shell was limited to two sizes, and the cement composition was varied in a limited range. Further research should explore a wider range of particle sizes and cement compositions to optimize the quality of the cement boards.

In conclusion, this study provides valuable insights into the effect of particle size and cement composition on the quality of cement boards produced from the candlenut shell. The findings of this research highlight the potential of utilizing waste materials as raw materials for cement boards and provide a foundation for further research in this area.
