"Harish Badami has taken over as CEO & MD from August 13, 2014 and Kuldip Kaura has demitted office as CEO & MD from the said date," ACC said in a statement.
The Board ACC Ltd, in which Swiss building material major Holcim has the majority stake, had in June approved Badami's appointment.
Immediately before joining ACC on August 1, 2014 Badami had served as Managing Director of Celanese India. He has held similar positions of President and Managing Director of Dow Chemical India, and Managing Director of Rohm and Haas India, before its acquisition in 2009 by Dow Chemical.
