CEMENTLESS PLASTIC PAVING BLOCK INNOVATION FOR ENVIRONMENTALLY FRIENDLY PEDESTRIAN AREA UTILIZATION

Abstract

Urban infrastructure development demands sustainable solutions to address environmental challenges, particularly in pedestrian areas where conventional cement-based paving blocks contribute to high carbon emissions and resource consumption. This study aims to develop and evaluate cementless plastic paving blocks as an eco-friendly alternative by utilizing recycled plastic waste. The research focuses on assessing the compressive strength and water absorption of paving blocks containing 25% recycled plastic. An experimental approach was employed, involving the fabrication and testing of samples. Compressive strength was measured using a Universal Testing Machine (UTM), while water absorption. The results indicate that the paving blocks achieved a compressive strength of up to 20.27 MPa, surpassing the standard requirement of 12.5 MPa, making them suitable for pedestrian applications. The low water absorption rate (0.43% - 0.96%) enhances durability and reduces slipperiness, though it necessitates effective drainage solutions to manage runoff. This study contributes to sustainable construction by offering an innovative paving solution that minimizes cement use, reduces plastic waste, and supports urban sustainability.
