PURPOSE: To obtain a highly durable mortar material having excellent shrinkability to stabilize the whole brick structure and suppress the loss of mortar joint. CONSTITUTION: This refractory mortar contains 0.1-40wt.% of zircon and/or titanium oxide in total and the remaining part consisting of magnesia and <=20wt.% of other refractory material. The zircon or titanium oxide thermally reacts with magnesia near the working wall surface to cause the expansion of brick. The mortar is softened to develop the shrinkability by the reaction of zircon or titanium oxide with magnesia to effectively absorb the expansion of brick and stabilize the brick structure. The durability of the mortar itself is also high because the reaction product suppresses the infiltration of slag. |
