The Influence of Palm Oil Shell Ash as an Additional Material in the Manufacture of Bricks

Introduction

The increasing demand for sustainable and environmentally friendly building materials has led to the exploration of alternative materials from waste sources. One such material is oil palm shell ash, a by-product of the oil palm industry. The utilization of oil palm waste as building materials is gaining attention, and the use of oil palm shell ash as an additional material in the manufacture of bricks is one area of research that has shown promising results. This study aims to investigate the effect of adding oil palm shell ash to a mixture of clay on the strength, water absorption, and density of bricks.

Oil Palm Shell Ash: Environmentally Friendly Solutions for Building Materials?

The oil palm industry is one of the largest producers of waste in the world, with millions of tons of oil palm shells generated annually. Traditionally, these shells are discarded or used as fuel, but recent research has shown that they can be used as a valuable resource in the production of building materials. Oil palm shell ash, in particular, has been found to have potential as a sustainable and environmentally friendly material for construction.

Methodology

In this study, a mixture of clay was used as the primary material for brick production, with oil palm shell ash added in varying proportions. The composition of the mixture was as follows:

0% oil palm shell ash (control group)
10% oil palm shell ash
20% oil palm ash
30% oil palm shell ash
40% oil palm shell ash
50% oil palm shell ash

The mixture was then dried for 28 days, after which the bricks were tested mechanically and physically according to applicable procedures. The tests included compressive strength, water absorption, and density.

Results

The results of the study showed that the addition of oil palm shell ash to the mixture of clay had a significant impact on the physical properties of the bricks. The compressive strength of the bricks with a mixture of oil palm shell ash in a 10% and 20% composition approached that of normal bricks. However, the use of oil palm shell ash also had an impact on the physical properties of the brick.

Physical Properties of Bricks with Oil Palm Shell Ash

The water absorption of bricks with oil palm shell ash was found to be higher than that of normal bricks, ranging from 15.03% to 23.13%. The density of the bricks with oil palm shell ash was also lower, ranging from 1.69 gr/cm3 to 1.41 gr/cm3 compared to normal bricks. The strength of the bricks with oil palm shell ash was also lower, ranging from 94HB to 83HB compared to normal bricks.

Discussion

The results of this study indicate that oil palm shell ash can be used as an additional material in the manufacture of bricks, but it should be considered the effect on the physical properties of the brick. Although the compressive strength of the brick with a mixture of oil palm shell ash in certain compositions approaches normal bricks, water absorption, density, and lower hit strength are significant concerns.

Conclusion

The use of oil palm shell ash as an additional material in the manufacture of bricks has shown promising results, but further research is needed to find the optimal composition of oil palm shell ash that can produce bricks with good strength and physical properties that are appropriate for construction purposes. This is important to ensure that the use of oil palm shell ash as building materials is not only environmentally friendly, but also safe and effective.

Recommendations

Based on the results of this study, the following recommendations are made:

Further research is needed to find the optimal composition of oil palm shell ash that can produce bricks with good strength and physical properties.
The use of oil palm shell ash as an additional material in the manufacture of bricks should be considered in conjunction with other sustainable materials.
The physical properties of bricks with oil palm shell ash should be carefully evaluated to ensure that they meet the requirements for construction purposes.

Future Research Directions

The use of oil palm shell ash as a sustainable and environmentally friendly material for construction is an area of research that has shown promising results. Future research directions include:

Investigating the optimal composition of oil palm shell ash for brick production.
Evaluating the physical properties of bricks with oil palm shell ash in different environmental conditions.
Developing new technologies for the production of oil palm shell ash-based building materials.

Limitations of the Study

This study has several limitations that should be noted. The study was conducted on a small scale, and the results may not be representative of larger-scale production. Additionally, the study only evaluated the physical properties of bricks with oil palm shell ash and did not consider other factors such as cost and availability.

Conclusion

In conclusion, the use of oil palm shell ash as an additional material in the manufacture of bricks has shown promising results, but further research is needed to find the optimal composition of oil palm shell ash that can produce bricks with good strength and physical properties that are appropriate for construction purposes. This is important to ensure that the use of oil palm shell ash as building materials is not only environmentally friendly, but also safe and effective.
