Composition and Classification of the Refractory Cement

Calcium Aluminate Cement, as one kind of unshaped refractory cement, it can be classified into two types: the common refractory cement (Al2O3 53~72%,CaO 21~35%) and the pure kind (Al2O3 72~82%,CaO 19~23%) according to its chemical component.

The former type refractory cement can be classified into two types, one is of low iron content (Fe2O3<2%) and the other is high iron content (Fe2O37~16%). The low iron type can also be classified by the content of Al2O3, such content of Al2O3 53~56% and CaO 33~35% is called bauxite cement. While the (Al2O3 59%~61%,CaO 27~31%) is called Aluminum-60 cement. Lastly, when the Al2O3 65~70%, CaO 21~24% is named as aluminate cement.

For the pure kind refractory cement, it can be classified into common type (Al2O3 72~78%) and ultrahigh aluminum type (Al2O3 78~85%).

Hardening Mechanism of Calcium Aluminate Cement

Setting and hardening rate of Calcium Aluminate Cement relates to curing temperature. For Mineral CA2, the setting and hardening rate speed up with the curing temperature rising. For mineral CA, the setting and hardening rate are some abnormal, more quickly when 20℃, change to be slow when 30℃ and re-quick when more than 30℃. It is very important to choose the suitable curing condition according to the change situation when the CalciumAluminate Refractory Cement hydras heating. As it’s hydrating will change with the different curing conditions. In the actual application, there always are some different marks for this refractory cement. The mark means the reaching strength after certain curing time. Thus this kind of refractory cement with CA as the main mineral generally adopts the mark strength after curing for three days. Then it with CA2 as the main mineral adopts the mark strength after curing for seven days.
