Abstract

Using plastic granules as replacement for concrete is an active topic of study due to the possible benefits in terms of sustainability and waste reduction. The consequences of substituting part of the coarse aggregate in concrete with recycled plastic granules are investigated in this research. In the research, recycled plastic granules are utilised in concrete mixes at varying percentages. Mechanical characteristics such as compressive strength and other properties were evaluated. The outcomes of this study indicates that when proportion of recycled plastic granules in the mixture increased, the characteristics experienced tremendous changes. As the recycled plastic granules in the concrete mix increased, the various strengths of the mixture decreased. The loss in strength was not significant for mixes with up to 20% replacement, suggesting that recycled plastic granules might be utilised. Other parameters like as workability, density, and water absorption were evaluated in addition to mechanical qualities. According to the results, as the number of recycled plastic granules grew, workability decreased, while density and other tendencies were also analysed. The findings revealed that increasing the quantity of recycled plastic granules lowered the workability while increasing the density.
