Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. 'Heat of hydration' is the term used to describe the heat released when cement reacts with water during the ...

The use of other constituents in cement and the reduction of the clinker-to-cement ratio means lower emissions and lower energy use. Ordinary Portland cement can contain up to 95% clinker (the other 5% being gypsum). The current average clinker-to-cement ratio over all cement types in the EU28 is 73.3%.
A few years later, in 1845, Isaac Johnson made the first modern Portland Cement by firing a mixture of chalk and clay at much higher temperatures, similar to those used today. At these temperatures (1400C-1500C), clinkering occurs and minerals form which are very reactive and more strongly cementitious.

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.

For example, CEM II/A-M (S-V-LL) 32.5 R is the abbreviation of early strength Portland composite cement of 32.5 MPa strength class, incorporating 6-20% granulated blast furnace slag, siliceous fly ash and
Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
