The water-to-cement ratio is 0.36 for all SCC mixes. Slump flow, V-funnel, and l-box tests were performed on fresh concrete to investigate the fresh properties and rheology of green SCC. A total of 250 cubic specimens of 10 × 10 cm², 60 cubic specimens of 15 × 15 cm², and 40 cylindrical specimens of 10 × 20 cm² for testing compressive strength, Rapid Chloride Permeability Test (RCPT), surface electrical resistance, water penetration depth under pressure, and half-hour water absorption to evaluate the durability properties of concrete, were sampled. From the obtained results, it was concluded that replacing the aggregate with FSiMnS provides better compressive strength results up to 18%, and somehow increase in durability test results, but has adverse effects on the workability parameters of SCC. Sirjan pozzolan has shown better performance than Khash pozzolan in all durability tests, while Khash pozzolan has higher initial compressive strength. https://ceij.ut.ac.ir/article_99620_3855280ae05920f6a6ea9cd8de4e3cc8.pdf
