What effects on strength of concrete using ordinary portland cement and sulfate resistance cement?

only concrete strength is different. SRC is having high strength

Sulfate Resisting Cement is a specially blended cement designed to improve the performance of concrete in sulfate environments and help improve durability.

Overall concrete strength in case of sulfate resisting cement is higher than the normal ordinary Portland cement.

W/C ratio generally play significant role of concrete strength whether ordinary or sulfate resistance cement.
