JSW Cement—the cement manufacturing unit of the JSW Group that is controlled by Indian billionaire Savitri Jindal and her family—is gearing up for a 36-billion-rupee ($412 million) IPO this week.

The IPO comprises the sale of up to 16 billion rupees ($183 million) of new shares, and up to 20 billion rupees ($229 million) by existing shareholders, according to a prospectus released by the company last week.

The offer to anchor investors will begin on Wednesday, while the public offering starts the following day. JSW Cement is tentatively scheduled to start trading on the Indian bourse on Aug 14.

Proceeds from the IPO will be used to fund the construction of a new cement plant in Nagaur, Rajasthan in northwestern India as well as repay debt and support the company’s working capital needs.

JSW Cement plans to nearly triple its annual production capacity to 60 million tonnes in the next few years to narrow the gap with bigger rivals such as tycoon Kumar Birla’s UltraTech Cement billionaire Gautam Adani’s Ambuja Cement.

JSW Group has also been expanding its other businesses. In June, JSW Paints agreed to buy a majority stake in Akzo Nobel’s India business in a deal valued at €1.4 billion ($1.6 billion).

Jindal is the chairwoman of JSW Group, which she inherited from her late husband, Om Prakash Jindal. She and her family have an estimated net worth of $36.6 billion, according to Forbes’ real-time data. Her son, Sajjan Jindal manages the group’s key businesses, including JSW Steel, JSW Cement, and JSW Paints.
