摘要

Driven by the environmental impact of excessive natural aggregate extraction, this research investigates the potential for partial replacement with various waste materials, including plastic, recycled concrete, glass, and ceramic. By systematically analyzing the influence of these incorporated waste materials on concrete’s workability, mechanical strength, and durability, the study aims to evaluate their effectiveness as sustainable alternatives. The research findings suggest promising opportunities for waste utilization, highlighting the need for identifying optimal replacement levels tailored to specific waste types and desired concrete properties. While the initial results are encouraging, further research is crucial to optimize mix design for consistent performance, ensure the long-term viability of these waste materials in real-world construction projects, and address potential regulatory and societal concerns associated with their incorporation. This comprehensive investigation seeks to pave the way for the sustainable utilization of waste materials in the construction industry, contributing to reduced environmental impact and responsible resource management.
