The Influence Of The Pet Plastic Waste Gradation As A Rough Aggregate On The Compressive Strength Of The Structural Mild Concrete
The Influence of Pet Plastic Waste Gradation as a Rough Aggregate on the Compressive Strength of the Structural Mild Concrete
Introduction
The increasing awareness of industrial waste management has led to the exploration of alternative materials to replace aggregates in concrete. One such ingredient that has gained attention is the plastic waste type PET (Polyethylene Terephthalate). This study focuses on the use of PET plastic waste as a rough aggregate in making structural lightweight concrete. The process of making coarse aggregate from PET plastic waste involves heating, cooling, and grinding to produce aggregates with varying sizes and form certain gradations.
The Purpose of the Study
The purpose of this study is to explore the process of making coarse aggregate from pet plastic waste, analyzing the strength of the resulting lightweight concrete, and understanding the effect of aggregate gradations on concrete compressive strength. Aggregate gradation variations are measured by the modulus modulus number (FM). The use of alternative materials to replace aggregates in concrete is increasingly popular, especially with an increase in awareness of the issue of managing industrial waste.
Research and Analysis Results
The results showed that the use of coarse aggregate from pet plastic waste with variations in gradations producing mild concrete with varied weight. For gradations (FM) 6.01, the resulting lightweight concrete weighs 1,741.23 kg/m³. With a gradation (FM) of 6.56, the weight increases to 1,784.69 kg/m³, and for gradations (FM) 7, weighing 1,801.48 kg/m³. However, in terms of compressive strength, the light concrete produced does not meet the standard of structural concrete compressive strength. The maximum pressure strength recorded is 16.57 MPa for the use of aggregates with gradations (FM) 7. As for gradations (FM) 6.01 and 6.56, the compressive strength value produced is 13.89 MPa and 16, 27 MPA.
According to SNI 03-3994-2002, the resulting concrete cannot be classified as a mild concrete construction because it does not meet the weight and compressive strength requirements that support each other. This shows that although the use of PET plastic waste as a rough aggregate offers an interesting alternative in waste management, its effectiveness in improving the quality of structural concrete still needs to be further evaluated.
Factors Affecting Compressive Strength
There are several factors that affect concrete compressive strength that uses aggregates from PET plastic waste. One of them is the area of the aggregate that lacks a strong confusion with cement paste, which is very important in determining the compressive strength of concrete. In addition, aggregate density is also a crucial aspect; Aggregates that are too light can produce concrete with a structure that is not dense, thus affecting the overall compressive strength.
The Importance of Aggregate Gradation
Aggregate gradation is a critical factor in determining the compressive strength of concrete. The gradation of coarse aggregate from PET plastic waste has a significant influence on the compressive strength of structural mild concrete. The results of this study show that the use of aggregates with different gradations produces concrete with varying compressive strength values.
Conclusion
In the conclusion, the gradation of coarse aggregate from PET plastic waste is proven to have a significant influence on the compressive strength of structural mild concrete. Although the use of PET plastic waste can help reduce waste and structural weight, the challenge to achieve the desired compressive strength must be overcome through further research and better development of methods. Innovation in the mixing technique and use of additional materials may be needed to increase the physical and mechanical characteristics of the concrete produced.

This study highlights the need for further research on the use of PET plastic waste as a rough aggregate in making structural lightweight concrete. Future studies should focus on developing new methods for producing coarse aggregate from PET plastic waste and improving the compressive strength of the resulting concrete.
