PROJECT ENGINEERING, MANAGEMENT AND IMPLEMENTATION

TISCO is largest industrial conglomerate and pioneer for steel production in India. Starting in 1911 the company branched off to multiple industrial sectors. In 1990 they decided to diversify in cement production and use slag, which is a waste by-product of steel manufacturing process. Holtec was engaged as prime-consultant. The split located plants were commissioned in 1993.

The clinkerisation plant (1.0 mio tpa) at Sonadih, Madhya Pradesh grinds 0.3 mio tpa of OPC and grinding plant at Jojobera, Bihar produces 1.45 mio tpa of PSC.

In 1999, after TISCO’s strategic decision to disinvest in cement sector, Lafarge India acquired the two plants.
