This study investigates the long-term mechanical performance of high-strength steel fiber-reinforced concrete (SFRC) incorporating calcined boron waste with increased amorphous content. Calcined waste was used as a partial cement replacement at ratios of 5%, 10%, and 15% to prepare the mixtures. The mechanical behavior was monitored over a three-year period through compressive, flexural, and splitting tensile strength tests. Results indicate that calcined boron waste significantly enhances long-term mechanical properties, with the 5% replacement ratio yielding the highest strength values. Consequently, calcined boron waste is identified as a high-potential additive for improving SFRC characteristics
