    Type I: Ordinary Portland Cement Suitable to be used in general concrete construction when special properties are not required. Type II: Modified Portland Cement Suitable to be used in general concrete construction. Main difference between Type I&II is the moderate sulfate resistance of Type II cement due to relatively low C3A content (%8).
