The first is the discovery of the production principle of white cement, which is obtained by using iron-free kaolin instead of clay. However, this different composition did not change the intrinsic properties of the cement, providing a strength capacity comparable to gray cement. The year 1908 witnessed the first industrial calcium alumina made with limestone and bauxite. High alumina cement, which is resistant to aggressive agents and high temperatures, has opened up multi-purpose usage opportunities such as being used as a high-performance binder or chemical reactant in many different application areas. Today calcium aluminates stand at the cutting edge of technological development in the construction field and have stimulated the development of many technological products such as special mortars, refractory mortars and others. Can be used for general purpose.
