Eight core sectors grew at a slower pace of 4.7% in October, chiefly due to subdued performance of cement, steel and refinery segments.
The eight infrastructure sectors -- coal, crude oil, natural gas, refinery products, fertilisers, steel, cement and electricity -- had clocked a growth of 7.1% in October last year.
Meanwhile, the industry ministry has revised downwards September growth print of these eight sectors to 4.7% from the earlier estimate of 5.2%.
Official data released this evening showed that cement production contracted by 2.7% as against an expansion of 6.2% in October 2016.
