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.
