5 CEMENT –HISTORY 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 about1000 tons of Portland cement. By 1918 three factories were established.
The common raw materials used for manufacturing of cement include limestone, shell, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.
Dangote Cement is a fully integrated cement company and has projects and operations in Nigeria and 14 other African countries.

Mixing and Blending for the manufacturing of cement Dry Process. In the dry process of cement manufacturing, workers first mine and crush raw materials such as limestone, clay, and sand, then transport them to a grinding mill where they dry and reduce them to a fine powder. They then store this dry powder, known as raw meal, in silos.

The invention of Portland Cement is generally credited to Joseph Aspedin, an English Bricklayer in 1824. The Portland name was given because its color resembled the stone quarried on the Isle of Portland off the British coast. In Germany and Belgium cement manufacturing started around 1855 In US manufacturing of cement started around 1870's

Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches.
The cement manufacturing process description illustrated here is derived from various literature sources. A comprehensive overview of cement manufacturing and technologies can be found in (CEMBUREAU, 1999; Duda, 1985; Environment Agency, 2001; IPPC, 2013; Karstensen, 2006).
