The Physical and Mechanical Properties of Cement Board from the Pencil Industry Waste with Various Raw Material Ratios and Density Targets
Introduction
In the industrial world, waste is often considered a problem that needs to be overcome. However, waste can also be converted into useful products, as shown in research by Yunida Syafriani Lubis. This study explores the use of pencil shavings from industry as raw material for cement boards. Through careful testing, this study aims to evaluate the physical and mechanical properties of the cement board produced with various raw material ratios and density targets.
The Importance of Sustainable Building Materials
The construction industry is one of the largest consumers of natural resources, and the production of cement boards is no exception. Traditional cement boards are made from a mixture of cement, sand, and water, which can have a significant environmental impact. The use of industrial waste, such as pencil shavings, as an alternative raw material can help reduce the environmental footprint of the construction industry. This study aims to investigate the potential of using pencil shavings as a sustainable building material.
Research Purposes
The main objectives of this study are to:
Determine the optimal ratio of cement and pencil shavings and the best density target for the physical and mechanical properties of the cement board produced . This will involve testing different ratios of cement and pencil shavings, as well as varying the density target, to determine the optimal combination for producing high-quality cement boards.Analyze the effect of raw material ratios and density targets to the quality of cement boards . This will involve evaluating the physical and mechanical properties of the cement boards produced, including their strength, durability, and density.
Methodology
In this study, the process of making cement boards was carried out with cold compaction techniques at a pressure of 25 kg/cm² for 10 minutes. The hardening process of the cement board is carried out in two stages. In the first stage, the board is left to dry in the air for 4-5 days. After that, the cement board is dried in the oven for 24 hours at 50 ° C. This method is designed to ensure the strength and durability of the resulting cement board.
Raw Material Ratios and Density Targets
The raw material ratio used in this study is 80:20 and 85:15, with a target density set each 1 g/cm³ and 1.2 g/cm³. As an acceleration in the process of making a cement board, magnesium chloride (mgCl₂) is used. The use of magnesium chloride can help improve the strength and durability of the cement board.
Results and Discussion
The results showed that the physical properties of the cement board produced meet JIS A 5417-1992 standards, which is a reference for the quality of cement boards in Japan. From the tests conducted, it appears that the ratio of raw materials has a significant influence on the strength of the cement board. Ratio 85:15 shows better results compared to the 80:20 ratio, especially in terms of mechanical properties.
The density target also plays an important role, where a density of 1.2 g/cm³ is proven to provide the best results. These results indicate that with the selection of appropriate density ratios and targets, pencil shavings waste can be used as an alternative raw material that is environmentally friendly for the production of cement boards.
Conclusion
This research opens new opportunities for the use of industrial waste, especially pencil shavings. With the right combination of raw material ratios and density target settings, the resulting cement board not only meets quality standards but also provides solutions to waste problems. Thus, further research in this field is highly recommended to expand applications and innovations in the use of industrial waste as sustainable building materials.
