Manufacture and Characterization of Concrete Polymers Based on Oil Palm Shells and Fiberglass with Epoxy Resin

Introduction

Innovative Materials for Sustainable Construction

The construction industry has been increasingly adopting innovative materials to reduce environmental impact and improve building performance. One such material is polymer concrete, a composite material made from a mixture of cement, aggregate, and polymer resin. In this study, we explore the manufacture and characterization of polymer concrete based on oil palm shells and fiberglass with epoxy resin. Our aim is to understand the effect of adding these materials on the physical and mechanical properties of the polymer concrete produced.

The Process of Making Polymer Concrete

Making polymer concrete is a multi-stage process that requires careful attention to detail. The first stage involves mashing and filtering oil palm shells and sand using 100 mesh sieves to ensure consistency in size. In the second stage, fiberglass is cut into fibers approximately 0.5 cm in length. The third stage involves mixing sand, palm oil shells, and fiberglass with epoxy resins to create a homogeneous dough. Finally, the mixture is inserted into a mold and heated at 90 °C for 20 minutes using the Hotpress method. The sample dimension used in this study was a block measuring 10 x 2 x 1 cm.

Composition and Testing Variations

The variation of the composition used in this study consists of the ratio of sand and epoxy resin (30:40) grams, oil palm shells in variations (30, 28, 24, 22, 20) grams, and fiberglass in variations (0, 2, 4, 6, 8, 10) grams. The parameters tested to determine the materials of the material include density, water absorption, porosity, flexural strength, compressive strength, and tensile strength.

The Importance of Material Composition

The composition of polymer concrete plays a crucial role in determining its physical and mechanical properties. The addition of oil palm shells and fiberglass can significantly impact the performance of the material. In this study, we investigate the effect of varying the composition of polymer concrete on its properties.

Characterization of Polymer Concrete

The characterization of polymer concrete involves testing its physical and mechanical properties. The parameters tested include density, water absorption, porosity, flexural strength, compressive strength, and tensile strength. These tests provide valuable information on the performance of the material and its potential applications.

RESULTS AND ANALYSIS

The results showed that the best composition for polymer concrete was obtained in the ratio (30, 22, 8, 40) grams. In this composition, polymer concrete has a density of 1.52 gr/cm³, porosity of 0.33%, water absorption 0.23%, flexible strength of 101.02 MPa, compressive strength 70.06 MPa, and tensile strength 4.28 MPa. These results indicate that the polymer concrete produced is not only lightweight but also has a waterproof capability and high compressive strength.

Advantages and Applications

The use of oil palm shells as raw materials in making polymer concrete provides additional benefits because the shell is abundant waste from the palm oil industry. By converting waste into value material, this research not only overcomes waste problems but also contributes to sustainable development.

The resulting polymer concrete has the potential to be used in mild construction applications, such as wall panels, decks, and other architectural elements that require material with low weight but still strong. The presence of fiberglass in the mixture also increases resistance to cracks and deformation, thus extending the life of the structure that uses this polymer concrete.

Conclusion

This study succeeded in showing that the combination of oil palm shells and fiberglass in making polymer concrete with epoxy resin can produce materials that are not only mild but also have excellent mechanical properties. This opens new opportunities for the use of agricultural waste and innovation in construction materials. This result is expected to encourage more research in the field of sustainable material and its application in the construction industry.

Future Research Directions

The results of this study provide a foundation for further research in the field of sustainable materials and their application in the construction industry. Future studies can investigate the use of other agricultural waste materials, such as rice husk or sugarcane bagasse, in making polymer concrete. Additionally, research can focus on developing new techniques for processing and characterizing polymer concrete.

Conclusion

In conclusion, this study demonstrates the potential of using oil palm shells and fiberglass in making polymer concrete with epoxy resin. The resulting material has excellent mechanical properties and can be used in mild construction applications. This research contributes to the development of sustainable materials and their application in the construction industry.
