PT Krakatau Semen Indonesia (KSI), a joint venture between state-owned steel maker PT Krakatau Steel and state-owned cement maker PT Semen Indonesia, has opened a new slag grinding plant.
Located on a 4ha plot in Cilegon, Banten, Indonesia, the IDR420bn (US$31.4m) project saw construction start in 2014. The grinding plant has a production capacity of 690,000tpa of ground granulated blastfurnace slag (GGBS) that will be used in cement manufacture.
"GGBS is a more stable product that can substitute for cements widely used in concrete structures for ports, bridges, roads and buildings," Krakatau Steel President Director, Mas Wigrantoro Roes Setiyadi, said at the inauguration of the plant on Thursday.
Krakatau Steel and Semen Indonesia each own a 50 per cent stake in the joint venture, in which 30 per cent of the investment came from the two companies and 70 per cent was financed by bank loans, reports The Jakarta Post.
