STUDY ON THE CEMENT QUALITY OF CONCRETE EQUIVALENT TO BLAST-FURNACE SLAG CEMENT TYPE A PRODUCED BY MIXING DIFFERENT TYPES OF CEMENT

Regarding cement equivalent to blast-furnace cement Type A, which is produced by mixing ordinary Portland cement and blast-furnace cement Type B from different manufacturers, it has been confirmed that the cement conforms to blast-furnace cement Type A specified in JIS R 5211 (blast-furnace cement) based on cement quality tests and the manufacturer’s test results sheets for the past five years.
