How Cement Is Made - Portland Cement Association

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

Role of lime stone in cement? - Page 1 of 2

Limestone is no more considered an inert material. World wide studies have shown that limestone takes part in hydration reaction and early strength development in cement. On the addition of limestone powder to cement, a reaction between CaCO 3 of limestone and aluminate phase of cement (C 3 A) takes place, which is quite similar to gypsum-C 3 A ...

Raw materials for cement manufacturing

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.
