History of Cement Industry in India - GKToday

2011-9-25  In 1924, India’s cement production was 267000 tons. However, initially this increased production could not reduce the imports and the industry suffered a rate war. This led to closure of many indigenous units. The Indian companies which were away from ports or commercial centres faced the lacational disadvantage.
