Billionaire Gautam Adani controlled Adani Group is in advanced talks with debt laden Jaiprakash Power Ventures to buy its cement unit, people familiar with the matter said. The ports-to-power conglomerate could pay about Rs. 5,000 crore($606 million) for a cement grinding unit and other smaller assets one of the people said asking not to be identified as the information is private.

The acquisition will be made by one of the cement units recently acquired by Asia's richest person, the people said, adding an announcement was expected as early as this week. While discussions are advanced, they could still be delayed or fall apart, the people said. Some reports said the deal earlier without disclosing a value.

The deal will help consolidate the Adani Group's sudden dominance in the cement sector, which started after it

Adani Group representatives declined to comment. Jaiprakash Associates representatives were not immediately available for a comment.

Separately, Jaiprakash Power Ventures said its board is looking to sell Nigrie cement grinding unit as well as other non-core assets, with naming any prospective buyers.
