Due to the porous structure of the insulating refractory bricks, if ordinary mortar is used for masonry, it will dehydrate quickly when it contacts brick surface, surface, failing to ensure, failing to ensure the depth of brick joints and the uniform combination, and ordinary mortar has no bonding strength at normal temperature . The air setting insulating refractory mortar made by our company applied with installation . It can level and adjust brick joints within 90+20 seconds ,and automatically harden by dehydration if it exceeds the time mentioned above. It is featured with good low-temperature strength, resulting in good structural performance of furnace brickwork.
