Cements in the 20th century The National Cement Share Company of Ethiopia 's new plant in Dire Dawa Calcium aluminate cements were patented in 1908 in France by Jules Bied for better resistance to sulfates.
By this means, sodium aluminate is formed; it is then extracted with water and precipitated either by sodium bicarbonate or by passing a current of carbon dioxide through the solution.
For special cements, such as Low Heat (LH) and Sulfate Resistant (SR) types, it is necessary to limit the amount of tricalcium aluminate (3 CaO·Al 2 O 3 ) formed.
The silicates are responsible of the mechanical properties of the cement, the tricalcium aluminate and the brownmillerite are essential to allow the formation of the liquid phase during the kiln sintering (firing).
The materials in cement clinker are alite, belite, tri-calcium aluminate, and tetra-calcium alumino ferrite.
