CEMENT MIXING ACTIVATOR OF SULFATE WITH GROUND GRANULATED BLAST-FURNACE SLAG
The present invention relates to a cement using a large amount of fine granules of blast furnace slag which comprises: 70 to 80 wt% of fine granules of blast furnace slag having fineness of 3,000 to 4,500 cm^2/g; 16 to 26 wt% of ordinary Portland cement (OPC); and 4 to 10 wt% of a sulfate-based activator. The present invention improves initial strength while maintaining long-term strength, which is an advantage of cement of the blast furnace slag; facilitates economically commercialized production due to having no increase in manufacturing costs by additional costs for pulverization, by using the sulfate-based activator; and has no bad influence on a human body and a working environment.
