<p>The generation of solid waste and the use of non-renewable natural resources in the mineral mining industry are environmental challenges that require the search for solutions that guarantee the application of circular economy and cleaner production principles. Studies on the reuse of granite waste slag (GWS) generated in this process can guarantee the minimization of the current environmental impact and contribute to the achievement of sustainability in the industrial sector. The objective of this study was to assess the feasibility of utilizing GWS in the construction of pavement bases and sub-bases, in combination with rice straw fibers (RSF) and concrete. To investigate the mechanical properties of recycled concrete utilizing mining waste, this study focuses on the influences of rice straw and GWS. The laboratory experimental program included the evaluation of material characteristics, compressive strength, and scanning electron microscope (SEM). Subsequently, study the correlation between compressive strength and different curing periods (7, 14, 21, and 28d), varying GWS contents (5, 10, and 15%)as well as varying RSF contents ( 0.3, 0.35, and 0.40%). The results indicate that the addition of 5 and 10% GWS yields predicted performance levels ranging from good to excellent, RSF content of 0.35%. The optimal curing periods for concrete was 28 d, the compressive strength of the specimen after 28d was 22.5&#xa0;MPa, which was 13.5% higher than the standard strength.</p>
