| Summary, etc. |
This study was conducted to evaluate the impact of Polyethylene (PET) bottles <br/>as a partial replacement of fine aggregate on the mechanical properties, durability, and <br/>overall sustainability of the coconut fiber reinforced concrete paving blocks (CFRCPB) <br/>and visually observe the chemical bonding of the resulting material. The experimental <br/>method and Randomized Complete Block Design (RCBD) were used to analyze, <br/>organize, and interpret the data collected from the conducted procedure for data <br/>gathering on the concrete paving block’s mechanical and physical properties. Statistical <br/>concentrations used were average, One-Way Analysis of Variance (ANOVA), and <br/>Least Significant Difference (LSD) tests.<br/>There were eight concentrations of the Coconut coir fiber reinforced concrete <br/>paving block with varying mass percentages of Polyethylene as partial replacement of <br/>fine aggregates ranging from 0%, 5%, 6%, 7%, 8%, 9%, and 10% (concentration <br/>groups). Material for concrete is a type I Portland cement of ordinary Portland Cement <br/>grade 43 conforming to ASTM Specification C150 and with a cement/water ratio of <br/>1:0.38 (cement: water) by ACI mix design. The concrete mix proportion followed the <br/>ACI 211 - Standard Practice for Selecting Proportions for Normal, Heavyweight, and <br/>Mass Concrete. The computed mix design is 1:1.08:1.44 (cement: fine aggregate:<br/>coarse aggregate).<br/>The study has demonstrated that incorporating Polyethylene (PET) bottles as a <br/>partial replacement of fine aggregates in coconut coir fiber-reinforced concrete paving <br/>blocks, particularly at a 5% replacement rate by mass, yields comparable performance <br/>to conventional Blocks. In contrast, adding only 3% coconut fiber indicates that <br/>coconut fiber alone weakens the concrete. The water absorption characteristics of the <br/>fiber-reinforced concrete paving blocks with PET replacement showed a significant <br/>deviation from those of conventional blocks. The dimensional tolerance of the paving <br/>blocks remained consistent with standards, this indicates that the use of PET does not <br/>compromise the overall quality or dimensional stability of the blocks. With that, PET <br/>bottles can be effectively utilized as a partial replacement of fine aggregates in fiberreinforced concrete paving blocks, and it was found to be that 5% replacement by mass <br/>is the optimum mixture. |
