Low cement castable is the castable whose CaO content less than 3%, usually the refractory cement dosage is from 3-8%, but high grade cement is needed to ensure the strength of the castable.
Comparing to common refractory castable, low cement castable has better performance in high temperature, and require less water, it makes the castable has lower porosity and higher density.
We have three classifications for low cement castable, bauxite based low cement castable, mullite based low cement castable and corundum based low cement castable.
As we all know, mullite is a very good kind of refractory raw material, the Al2O3 content is not very high, but the strength, wear resistance and the stability in high temperature is better than bauxite.
You can find the technical sheet data of low cement castable(mullite based) as below:
Service Temp ℃
Bulk Density (g/cm3)
(Dried at 110℃)
Max Grain Size (mm)
Water % (Typical)
1. Above are average typical test data subject to reasonable variations.
2. Type of Mixer VAM with 33RPM.
3. CCS-Cold Crushing Strength. MOR-Modulus of Rupture. P-Preferred. V-Vibration. T-Tamping.
Customization is welcome, you can send your required specification, we will make high quality castable as per your request.
Why Choose Us?
As we all know, raw material, formula, execution of the formula will decide the quality of castable.
In Tashan, we have our own lab to test the raw material to make sure all of them are high quality. And we have our stable supplier of raw material and have worked with them for more than 10 years.
Our factory are founded in 1998, with 20 years experiences of castable, and our engineers also worked in this area for more than 30 years, we believe our technical support and formula are top level. We produce castable using our production line, the whole line is controlled by computer to make strict execution of the formula.
