Abstract :
    In this research, an experimental study was done between compressive strength and rapid chloride penetration test (RCPT) in high-strength concrete (HSC) specimens containing silica fume (SF) and fly ash (FA). 7 concrete mix designs were made with a constant water-binder ratio of 0.28. The mixes designs include reference (Ref), the mixes containing SF as 5%, 10% and 15% and also FA as 15%, 25% and 30% replaced with Type II of Portland cement produced in the factory of Khouzestan province in Iran. The compressive strength and RCPT tests were done. Curve fitting between compressive strength and flow current of the HSC specimens were drawn at the ages of 28 and 91 days. The fitting results showed that there are proper relationships between compressive strength and flow current for some of HSC mix designs, although there were not acceptable relationships for some of them.
