1.Low Content of CaO
2.Excellent Mid-Temp Crushing Strength
3.Excellent High Temp Resistance
.Excellent Wear Resistance

Categories: Low Cement Castable, Unshaped Refractory Materials

Product Description

Low cement castable is based on the use of low calcium aluminate cement content, and they are used in many applications that require high refractoriness, corrosion resistance and abrasion resistance. They possess a uniform structure with low porosity; have high temperature strength throughout the low and intermediate temperature range.
The content of CaO of low cement castable is usually less than 3%,so it insure the castable have a good strength in mid-temperature.
