Effects of waste plastics as partial fine-aggregate replacement for reinforced low-carbon concrete pavements

Using waste plastics as a partial natural aggregate replacement and monitoring strength workability reduction in pavement structures is vital to net-carbon zero. This study explores the utilisation of plastic fine medium-strength reinforced concrete pavements, for improving performance intrinsic reasoning observed performance. Various weight fractions fines were substituted by same aggregates ranging from 5–15% according appropriate standards (Eurocodes British Standards). The physical mechanical properties composites analysed. results indicated that use polymeric materials contributed decrease workability, compressive push-out bond between steel reinforcement concrete. Despite these trends, 5% with surpassed all feasibility criteria. Furthermore, using 10% was deemed feasible non-structural applications such roads, facades. outputs have demonstrated environmental engineering concepts tackling waste, providing an alternative conventional aggregate. Environmental benefits can arise due removal potentially hazardous entering ecosystems well minimising dredging global sand reserves.
