Simultaneously, cemented rock fill (CRF) implemented in underground stoping mining methods presents tensile strength limitations, resulting in stability issues during horizontal (overhead) exposure. As such, there is benefit to reinforce CRF against tensile stresses. Given the vast volume of CRF used in mining operations, it is difficult to find a suitable reinforcing material that is also economical and sustainable. This study explores the incorporation of waste tyre rubber into CRF to develop tyre-enhanced cemented rock fill (TCRF), addressing both waste tyre recycling and CRF strength deficiencies. Large-scale experimental investigations, including compressive and tensile strength were conducted including waste tyre rubber from 5.5 % to 33 % of the cemented rock fill by volume. Results indicate that while the inclusion of waste tyre rubber reduces compressive strength and modulus, it significantly enhances tensile strength—a crucial parameter for backfill stability. A mix design of 3 % cement and 22 % waste tyre rubber achieved a tensile strength comparable to conventional CRF with 5 % cement, enabling potential cement savings of AU$ 8 per cubic meter of CRF through the removal of 2 % cement content for the same performance. Furthermore, the waste tyre rubber addition improved ductility and post-failure strength behaviour, further increasing the stability of backfilled exposures. As such, this research highlights TCRF as a sustainable and cost-effective solution for underground mining backfill, advancing waste tyre recycling and optimizing material cycles in mining operations.</div></div>","PeriodicalId":100256,"journal":{"name":"Cleaner Waste Systems","volume":"11 ","pages":"Article 100321"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study identified 17 technological barriers to constructing ZCBs based on previous research, which were then used to create an online survey for distribution to construction professionals.

The exploratory factor analysis extracted 4 valid components: 1) inadequate technical support, 2) insufficient knowledge and infrastructure, 3) poor resources and immaturity, and 4) inadequate research and practical effort. After that, partial least squares structural equation modeling indicated that inadequate technical support has the strongest causal relationship compared to the other components. Meanwhile, the valid components revealed 4 configurations, offering a deeper understanding of the technical support model for ZCB construction. The present study provides a technical support model that can enhance understanding of the technological barriers to constructing ZCBs.
