Abstract: The paper aims to investigate the mechanical properties and microstructure of sulfur polymer composite (SPC) containing basalt fiber (BF). The compressive strength f c , splitting tensile strength f t , and flexural strength f f of SPC were tested at different BF contents of 0–3% and aspect ratios of 353 and 706. Meanwhile, the microstructure characteristics of SPC, i.e., the interfacial transition zone (ITZ) structure of SPC, bonding of BF with SPC, pore size distribution, and porosity, were analyzed. The results indicated that the inclusion of BF lowed the compressive strength of SPC; for SPC at a given BF content, the f c with 706 l/d was lower than that with 353 l/d. Meanwhile, the f t and f f of SPC with 353 l/d increased with BF content; for l/d of 706, the f t and f f increased with BF content before 2.5% then decreased with the increase in BF content; compared to 353 l/d, 706 l/d was more effective to improve the f t and f f of SPC. Additionally, an appropriate amount of BF was beneficial to improve the ITZ structure of SPC and bonding performance between BF and the matrix, and the porosity and pore size of SPC increased with BF content and l/d.
