Refractory Cements and Moldables in the Aluminum Industry
Oct 19 2018 · Microsilica can reduce the cement content of refractory castables due to the small particle size. It can also reduce the open porosity from about 20-30 to 8-16 and the drop in mechanical strength. Microsilica is thus added to alumina-based refractories to improve the mechanical properties at lower cost. However microsilica is believed to

Jun 01 2013 · This paper investigates the effects of AlPO 4 addition on the corrosion resistance of andalusite LCC refractories. Corrosion tests using the Alcoa cup test (850 °C and 1160 °C for 150 h and 72 h respectively) were conducted to determine the extent of penetration.The addition of AlPO 4 was shown to improve the corrosion resistance of the castables in contact with molten Al-alloy.

Process for applying low-cement castable refractory
Although low-cement castables have physical properties that are superior to conventional castables their use has been limited by a number of factors. First because of the small amount of cement in the castable material it must be pre-mixed with a measured amount of water for several minutes to activate the low-cement system.
