Lightweight Concrete Panel Wall CLC with HDPE Plastic Waste and Reinforcement of Wiremesh: A Sustainable Solution for the Construction Industry

Introduction

The world is facing a significant challenge in dealing with the increasing amount of plastic waste. According to the World Economic Forum, the consumption of plastic has increased by 5.2% each year, resulting in a staggering 64.5 million tons of solid waste in Indonesia alone, with around 80% of it consisting of plastic. In an effort to overcome this problem, researchers have been exploring innovative solutions, including the use of HDPE (High-Density Polyethylene) plastic waste as an alternative material in the manufacture of CLC (Cellular Lightweight Concrete) lightweight concrete panel walls.

The Problem of Plastic Waste

The issue of plastic waste is not only an environmental concern but also a significant economic burden. The production, disposal, and management of plastic waste have become a major challenge for governments and industries worldwide. In Indonesia, the amount of plastic waste has reached alarming levels, with the majority of it ending up in landfills or oceans, causing harm to the environment and human health. Therefore, finding innovative solutions to reduce plastic waste is crucial for a sustainable future.

The Use of HDPE Plastic Waste in CLC Lightweight Concrete Panel Walls

This study focuses on the influence of HDPE plastic waste substitution as a fine aggregate on the walls of a lightweight concrete panel CLC, both with or without reinforcement of Wiremesh. The tests carried out include analysis of specific gravity, compressive strength, and flexible strength from the panel wall. HDPE plastic waste used has a size between 1.18 mm to 4.75 mm, with a variation of use of 0%; 0.75%; and 1.5%. The process of making this panel wall uses a pre-Foaming method, where foam is produced first before mixing with cement and sand, without using a foam generator. The panel wall is printed with a size of 60 x 20 x 10 cm and left at room temperature before being tested after 28 days of age.

The Results of the Study

The results of the study show that the substitution of HDPE plastic waste can lose the specific gravity of the panel wall. HDPE waste variations at 1.5% with additional wiremesh reinforcement produce a maximum compressive strength of 1.56 MPa and a maximum flexural strength of 1.454 MPa. Interestingly, the reinforcement of Wiremesh on the panel wall does not have a significant impact on the compressive strength, but has a positive effect on flexible strength.

The Significance of the Study

According to SNI 03-3449-2002, the panel walls studied can be categorized as very light concrete, which is suitable for isolation. This is an added value considering the use of HDPE plastic waste not only provides a solution to reduce waste, but also provides alternative sustainable construction materials. With the increase in awareness of the importance of the environment and sustainable development, the use of plastic waste in construction can be an innovative step that not only reduces pollution, but also supports the efficiency of resources.

Conclusion

This study demonstrates the potential of using HDPE plastic waste as a sustainable alternative material in the manufacture of CLC lightweight concrete panel walls. The results show that the substitution of HDPE plastic waste can reduce the specific gravity of the panel wall, while also increasing its compressive and flexural strength. The use of wiremesh reinforcement has a positive effect on the flexible strength of the panel wall. This research opens the way for further research and extensive application in the construction industry in Indonesia, providing a sustainable solution for the future of development.

Recommendations

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

  • Further research should be conducted to explore the potential of using HDPE plastic waste in other construction materials, such as bricks and blocks.
  • The use of wiremesh reinforcement should be investigated in more detail to determine its optimal application in CLC lightweight concrete panel walls.
  • The development of new technologies and manufacturing processes should be encouraged to improve the efficiency and sustainability of the construction industry.

Future Directions

The use of plastic waste in construction is a rapidly growing field, with many researchers and industries exploring innovative solutions to reduce waste and promote sustainability. This study demonstrates the potential of using HDPE plastic waste as a sustainable alternative material in the manufacture of CLC lightweight concrete panel walls. Future research should focus on exploring the potential of using plastic waste in other construction materials, as well as developing new technologies and manufacturing processes to improve the efficiency and sustainability of the construction industry.
