Cement Additive
The cement industry presents one of the most energy-intensive sectors within the Indian economy. Increases in productivity through the adoption of more efficient and cleaner technologies in the manufacturing sector will be effective in merging economic, environmental, and social development objectives.
The final section therefore examines the ongoing changes in the cement industry structure. It compares world best technologies to Indian technologies and identifies potentials and barriers to the achievement of efficiency improvements.
Cement production is highly energy intensive and involves the chemical combination of calcium carbonate (limestone), silica, alumina, iron ore, and small amounts of other materials. Cement is produced by burning limestone to make clinker, and the clinker is blended with additives and then finely ground to produce different cement types.
