| Summary, etc. |
The improper disposal and management of plastic waste present a significant issue in the Philippines, necessitating urgent solutions. This research explores the feasibility of incorporating shredded polyethylene terephthalate (PET) bottles as an additive in concrete paving blocks for walkways and parking areas designed for minimal load. Utilizing an experimental approach, six groups were established under a randomized complete block design: a control group (C0) without PET and five concentration groups (C1, C2, C3, C4, C5) with 1%, 2%, 3%, 4%, and 5% PET additives, respectively. The shredded PET was added volumetrically to an M20 concrete mix with a cement, fine aggregate, and coarse aggregate ratio of 1:1.5:3 and a water-cement ratio of 0.68, using Type I Portland Cement. Compressive strength was tested at 7, 14, and 28 days of curing, with three 6” by 12” cylindrical samples per curing age per group. Additionally, two block sizes, Block 1 and Block 2, were assessed for water absorption, density, and dimensional deviations after 28 days. ANOVA and LSD tests were used to analyze the differences in properties across groups. Results showed that the C3 group, with 3% PET, demonstrated optimal performance, exhibiting higher compressive strength at 7 and 14 days compared to the control, and a marginal difference at 28 days. This study concludes that C3 provides an optimal mixture for sustainable concrete paving blocks, meeting standard physical and mechanical properties and offering a viable solution for green concrete production. It is recommended that future research explores the long-term durability and environmental impact of using PET in concrete, as well as its potential applications in larger structural projects. |
