Associated Cement Companies Ltd (ACC) India's second largest cement maker, plans to raise prices by 5 to 10 rupees ($1= INR45.53) per 50kg bag later this month due to stronger demand, a company executive said Thursday.  "There has been an improvement in cement demand since December and given the positive upswings in the economy there is scope for a 5 to 10 rupees hike," said the executive, adding that the increase would represent a seven per cent rise on existing prices. Cement prices vary from state to state depending on the consumption. In Mumbai cement is at INR153 per bag, while in New Delhi it's INR121.  The executive said cement consumption is picking up nationwide due to state-sponsored road projects and gains in the broad economy.
