Refractory cement is an important refractory material with stable performance and good effect. Usually customers use this product directly or as raw material for other monolithic products. For example, when manufacturing refractory castable, refractory mortars, refractory ramming mass and other products, adding refractory cement as aggregate can achieve good high-temperature working performance.
3 Different Types of Refractory Cement for Sale
CA50 Refractory Cement
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 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
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;
