Abstract

This article aims to evaluate the performance at high temperatures of the composite of iron ore tailings and cement through incombustibility tests. This composite is employed in brick manufacturing. Iron ore tailings are a byproduct of the mining industry, and their application in construction has aroused interest due to their potential to enhance material properties such as mechanical strength and durability. In this study, incombustibility tests were conducted to investigate the response of the composite under high-temperature conditions. The test results demonstrated that the composite exhibits satisfactory incombustibility properties at elevated temperatures, maintaining its structural integrity during exposure to intense heat. These findings suggest that the composite could serve as a viable and promising alternative in the production of fire-resistant construction materials. However, the significant 67.5% loss of compressive strength observed under extreme heat conditions notably compromises its structural load-bearing capacity, underscoring the need for a more rigorous evaluation when utilizing the composite in self-sustaining construction elements in such environments.
