The importance of this research lies in reducing environmental pollution by reducing CO2 emissions associated with cement production, which is used as a bonding material in the concrete industry; it has been replaced by slag or other geopolymer materials. This work represents an attempt to investigate the possibility of producing SIFCON concrete based on slag, where two types of fibers (Hooked steel fiber and straight steel fiber) in three ratios (5%, 15%, and 15%). Each type of fiber was used independently, and the other was mixed with the two types. The flow table test was used to choose the appropriate mixture. Some mechanical tests were performed, such as (compression strength test, splitting tensile strength test, flexural strength test, and impact test) at 28 days of age. The best compressive strength value was obtained when using 10% of straight steel fibers. The best results were obtained using 10% of hooked steel fibers when examining flexural and splitting strength. When examining impact strength, the best results in preventing cracks occurred by using 10% of straight steel fibers, while in terms of ultimate failure, they were in hooked steel fibers at a rate of 10%.
