Refractory researchers studied the effect of the amount of water added in cement on the thermal expansion behavior of alumina-magnesia castables after high-temperature firing. The results show that as the amount of cement increases the phases of CA2 and CA6 in the sample increase and the linear change rate of the sample increases after high
