The JV owns 60 per cent of Palanca Cimentos, while Gema owns the remaining 40 per cent.
The plant, to be located in the Benguela region, is expected to be built in the next three years and supply about 25 per cent of the cement to the Angolan market.
The plant will produce 600,000t of cement in the first year, 800,000t in the second and about 1.2Mt in its third year.
