Introduction

The palm oil processing industry generates a significant amount of waste, including palm shells, which are often discarded or burned. However, these waste materials have great potential to be used as reinforcing fillers in cement composite, reducing the volume of waste and promoting the principles of the circular economy. This study examines the effects of the intercalization of Ca2+ and Fe3+ ions on the surface of the palm shell to increase the strength and performance of cement composite.

Background and Literature Review

Cement composite is a widely used building material, but its mechanical and chemical properties can be improved by incorporating reinforcing fillers. Palm shells, with their high silica content and porous structure, have been identified as a potential reinforcing filler material. However, the surface modification of palm shells is necessary to increase the bond between the palm shell and the cement matrix. Intercalization of metal ions, such as Ca2+ and Fe3+, has been shown to improve the mechanical and chemical properties of cement composite.

Surface Modification and Ion Intercalization

The process of modification of the surface of the palm shell is carried out with the aim of increasing the bond between the palm shell and the cement matrix. This process is followed by intercalization of Ca2+ and Fe3+ ions to increase the strength and resistance of cement composite. Intercalization is the process of inserting metal ions into the structure of palm shells, which can improve the mechanical and chemical properties of the material.

Experimental Methodology

The experimental methodology involved the preparation of palm shell samples, which were then modified by intercalization of Ca2+ and Fe3+ ions. The modified palm shell samples were then mixed with cement and sand to form cement composite boards. The boards were then tested for their mechanical properties, including compressive strength and load value.

Testing and Analysis Results

The test results show that the intercalization of Ca2+ and Fe3+ ions has a significant effect on increasing the compressive strength of cement composite. The Ca2+ cement board with a ratio of 1: 3 (cement: shell) shows the best results with a load value of 5.67 kgf, stroke 1.51 mm/minute, and compressive strength of 3,755 kg/mm2. The Fe3+ cement board with a ratio of 1: 2 (cement: shell) gives the best results with a load value of 7.57 kgf, stroke 1.56 mm/minute, and compressive strength of 4,852 kg/mm2.

Comparison of Results

The test results show that the intercalization of Fe3+ ions has a more significant effect on increasing compressive strength compared to the intercalization of Ca2+ ions. This shows that Fe3+ ions are more effective in strengthening bonds between particles in cement composites.

Implications and Potential Development

Utilization of palm shells as a material for filling cement composites has several positive implications. First, the use of palm shell waste as building materials can reduce the volume of waste and encourage the principles of the circular economy. Second, the intercalization of metal ions on the surface of the palm shell can increase the strength and resistance of cement composites, open up opportunities for the development of stronger and durable building materials.
