Vietnam’s cement demand is estimated at between 28-28.5Mt this year and the country will have to import 4.5Mt of clinker, said the Ministry of Industry.   The Vietnam Cement Corp (VNCC) can provide around 12-12.2Mt, other joint ventures 8.5-8.6Mt, shaft kilns 4.1-4.2Mt and grinding stations 3-3.1Mt, the ministry said.   The Ministry of Construction forecasts cement consumption volume in March would sharply increase over last month. VNCC has sold more than 30,000t of cement per day since early this month, up 4000t over February’s average volume, of which northern provinces consumed nearly 20,000tpd.    Despite growing cement demand, VNCC has asked its affiliates not to increase prices. Last year, the country imported 4.2Mt of clinker and produced 16.4Mt domestically.
