New Delhi: Eight core industries grew at a slower pace of 4.7 per cent in October, chiefly because of a subdued performance of the cement, steel and refinery segments.

The eight infrastructure sectors - coal, crude oil, natural gas, refinery products, fertilisers, steel, cement and electricity - had clocked a 7.1 per cent growth in October last year.

The September growth figure has been revised to 4.7 per cent from the earlier estimate of 5.2 per cent.

Cement production contracted 2.7 per cent against an expansion of 6.2 per cent in October 2016. Steel output slowed to 8.4 per cent last month compared with 17.4 per cent a year ago. Growth in refinery output at 7.5 per cent was lower than 12.6 per cent a year ago.
