Manufacture and Characterization of Polymer Concrete using Volcanic Ash of Sinabung and Bamboo Powder as an Aggregate with Epoxy Adhesive

Introduction

The construction industry has been shifting towards the use of sustainable and environmentally friendly building materials in recent years. One of the innovative materials that have gained attention is polymer concrete, which is made from a combination of volcanic ash, bamboo powder, and epoxy resin. This study focuses on the manufacture and characterization of lightweight brick using these innovative materials. The addition of bamboo powder to volcanic ash has been shown to reduce the density and mechanical properties of the resulting brick, while increasing water absorption and material porosity. In this article, we will discuss the manufacture and characterization of polymer concrete using volcanic ash of Sinabung and bamboo powder as an aggregate with epoxy adhesive.

Materials and Methods

The materials used in this study include volcanic ash from Sinabung, bamboo powder, and epoxy resin as a binder material. A variety of bamboo powder compositions was added, ranging from 0.5 to 30 grams of the total weight of volcanic ash used. The proportion of epoxy resin used is 50% of the total mixture of volcanic ash and bamboo powder. The characterization process includes testing physical and mechanical quantities such as density, water absorption, porosity, flexural strength, and compressive strength.

Physical and Mechanical Testing Results

The test results showed that the density value obtained ranges from 1,5966 to 1,4403 g/cm³. The absorption of the Batako water produced varies between 0.054% to 0.357%, while the porosity is at 0.087% to 0.515%. For mechanical properties, measured compressive strength ranges from 49.574 MPa to 12,941 MPa, and flexural strength is in the range of 38,086 MPa to 11,930 MPa.

Analysis of the Effect of Adding Bamboo Powder

From the results of the analysis, it appears that the addition of bamboo powder tends to reduce the density and mechanical properties of the resulting brick. On the other hand, the addition of bamboo powder actually increases water absorption and material porosity. This shows a significant influence between the proportion of bamboo powder on the physical and mechanical characteristics of polymer concrete.

Discussion

The decrease in density can be interpreted as success in creating lighter materials, which certainly have wider applications in building construction. Conversely, increased water absorption and porosity can provide benefits in terms of brick ability to adapt to environmental humidity, but also a challenge to maintain structural strength.

Potential of Applications in Construction

Polymer concrete material with a mixture of volcanic ash and bamboo powder has excellent potential for use in various construction applications. The advantage of this brick is light, environmentally friendly, and can provide good insulation. Given the current trend towards the use of more sustainable building materials, the development of this lightweight brick can be one of the solutions to meet the needs of the construction industry.

Conclusion

Research on the manufacture and characterization of polymer concrete using volcanic ash and bamboo powder opens new opportunities in the use of innovative building materials that are not only efficient but also more environmentally friendly. Through further research, it is expected to find optimal formulas to improve mechanical properties while maintaining mild and environmentally friendly.
