India’s core sector output rose 3.2 per cent in August thanks to a sharp rise in steel production and a pickup in cement, suggesting a lift in infrastructure and construction activity, reports the Economic Times. Experts said the data was positive but not vigorous enough to suggest a dynamic revival in industrial activity. Cement output was up 3.1 per cent compared with a 1.4 percent rise in July, data released by the commerce department said. July core sector growth was revised down to 3 per cent from the 3.2 per cent estimated initially. The index measures output in eight infrastructure sectors — steel, cement, coal, refining, natural gas, crude oil, fertilisers and electricity generation.
