Manufacture of cement | Fun Science

Manufacture of Cement. To manufacture cement first of all limestone is added into the clay in proportion of 3:1 by weight. This mixture of limestone and clay is then dried and crushed to get a fine powder called ‘raw meal’.The raw meal is then added into a rotary kiln through a hopper as shown in figure.

Understanding Limestone in Cement| Concrete

2015-3-26 · The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation ...

Concrete With Limestone Calcined Clay Cement | Concrete ...

Cement is normally made from Limestone, Silica, Alumina and Gypsum, but when all these ingredients are mixed at a temperature of 1500o C, it causes an emission of CO2 on environment. To reduce this, the researchers found that the use of clinker should be reduced. And here the answer is Limestone Calcined clay cement.
