Key Points

The aim is to evaluate the quality of cement equivalent to blast-furnace cement Type A made by combining different cements.
Quality tests were conducted on cement samples from multiple manufacturers.
Manufacturer’s test results over the past five years were reviewed.
Cement was assessed against JIS R 5211 standards.”
Cement was verified to conform to JIS R 5211 specifications for blast-furnace cement Type A.
Consistency in quality among different manufacturers was observed.
