International Seminar on Frontiers of Ceramic and Material Technologies for Cement Industries (CemSem 2014)

摘要

Manufacturing of cement is an energy-intensive process, with thermal and electrical energy together accounting for nearly 40 % of operating costs. This energy load is justified because cement formation requires long retention times at very high temperatures. Demand for cement is mainly concentrated in the housing sector, contributing as high as 64-67 % of total demand. In a developing nation like India, the cement industry plays an important long-term role in the country's infrastructure development. India is the second largest producer of cement in the world, second only to China, with a current capacity of ~370 MT. This is expected to grow to 550 MT by FY 2020, with the top 20 cement companies accounting for almost 70 percent of the total cement production. The Indian cement and gypsum industry growth was driven by more than two billion dollars of foreign direct investment during the period from 2000 to 2014. The government of India also facilitated expansion of the industry by increasing its investment in infrastructure and approving the investment schemes of private players. In view of ever-increasing industrial activities in real estate, construction and infrastructure, and the development of Special Economic Zones across the country, the demand for cement in India is slated to further increase in coming years.
