to determine the effects of using a byproduct on the manufacturing process, cement performance and facility emissions. Portland cement is the basic ingredient of concrete. Concrete, one of the most widely used construction materials in the world, is formed when portland cement creates a paste with water that binds with sand and rock to harden.
the process and chemistry of cement manufacturing was obtained from the Portland Cement Association, a research and market development organization representing 75% of the Portland cement producers in the United States.
Manufacturing of cement involves various raw materials and processes. Each process is explained chemical reactions for manufacture of Portland Cement. Cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone.

In India, Portland cement was first manufactured in 1904 near Madras, by the South India Industrial Ltd. But this venture failed. Between 1912 and 1913, the Indian Cement Co. Ltd., was established at Porbander (Gujarat) and by 1914 this Company was able to deliver about 1000 tons of Portland cement.
Methods of cement manufacturing 1- Wet process ___ grinding and mixing of the raw materials in the existence of water. 2- Dry process ___ grinding and mixing of the raw materials in their dry state. The process to be chosen, depend onthe nature of the used raw materials.
