Refractory Cement

Refractory Cement could be divided into aluminous refractory cement and low lime aluminate refractory cement. These two kinds of cement both have excellent refractoriness, compressive strength, and resistance to erosion. And they could be used in many industries.

Types of Refractory Cement for Sale

CA50 Refractory Cement

CA50

The setting time of CA50 is short. After the solidification, the hardness can quickly reach to 70%. This type can resist chemical and biological erosion, especially sulfate erosion. It also resists high temperatures. The use temperature could reach 1500℃.

  • Al2O3: ≥50-53.5%;
  • Initial Setting Time: ≥45-90min;
  • Final Setting Time: ≤6min;
  • 72H Compressive Strength: 55-82MPa;

CA70 Refractory Cement

CA70

CA70 could divided into CA70S and CA70W. CA70S does not need to add any blender while using. It has good mobility and setting time in a long time. This type is usually used in summer. CA70W has a fast setting time and great hardness at early stage. It is most suitable used in winter and other urgent works.

  • Al2O3: ≥68.5-71.5%;
  • Initial Setting Time: ≥120-240min;
  • Final Setting Time: ≤90-300min;
  • 72H Compressive Strength: 45-65MPa;

CA80 Refractory Cement

CA80

CA80S has good mobility and a long setting time. Like the ca70s, ca80s used in summer. It can used in some works that need a long working time. CA80W is used in winter. It has a normal setting time and good compressive strength. And this type could resist pressure better than other refractory cement.

  • Al2O3: ≥78-81%;
  • Initial Setting Time: ≥30-150min;
  • Final Setting Time: ≤90-350min;
  • 72H Compressive Strength: 40-50MPa;
