Specialty Cement -VCEM GGBS Ground Granulated Blastfurnace Slag (GGBS)

EnGro is the pioneer and leading manufacturer of Ground Granulated Blastfurnace Slag (GGBS). In North Asia alone, we currently produce over 9.5 million tons of GGBS annually.

Ground Granulated Blastfurnace Slag (GGBS or GGBFS) is obtained by quenching molten iron blastfurnace slag (a by-product of iron and steel making) in water or stream, to produce a glassy granular product that is then dried and ground into a fine powder.

Through intensive research and development, we developed a patented high-pressure roller press process that ensures high fineness, high reactivity, good particle size distribution, and quality consistency. With state-of-art processing equipment, the physical and chemical properties of GGBS/GGBFS are continuously monitored and controlled during manufacture to ensure that the finished product complies with national and international standards (e.g. GB/T 18046, KS F 2563, BS 6699, SSEN 15167 and ASTM C989).
