What is Cement ?
Portland cement is obtained by mixing the right proportions of limestones and clays, grinding them very finely to obtain the rawmix, and then roasting the rawmix in a kiln to obtain clinker (around 1,450ºC for grey clinker).
The rawmix is preheated in vortex preheaters fed with hot air from the kiln head, and it is then roasted in a rotary kiln.
The product consists basically of calcium silicates, which are the main source of strength, and other compounds such as tricalcium aluminate and Tetracalcium alumino-ferrite, which are used in cement-making to reduce the temperature at which calcium silicates are formed, as well as other oxides (MgO, SO3, Na2O, K2O) obtained from the raw materials or the fuel.
