Product Description
Refractory cement is also known as high-temperature cement. It is made of high-quality bauxite and high-quality lime, both of which are combined with appropriate amount of ingredients in a certain proportion. The refractory degree of refractory cement is not less than 1580℃ (2876℉). It can be divided into aluminate refractory cement, low-calcium aluminate refractory cement, calcium-magnesium aluminate cement, and dolomite refractory cement according to different compositions.
Refractroy Cement CA50
Aluminate cement CA50 series products are based on natural high-quality bauxite and limestone as raw materials, calcined at high temperature to form a clinker with one calcium aluminate (CA) and one calcium dialuminate (CA2) as the main mineral phase, and then ground to the best particle size distribution of water-hard cementitious material.
