Description
1.Features of mortar
Fire-resistant and refractory mortar is a fire-resistant and refractory special mortar composed of high-temperature resistant inorganic refractory materials. Fire resistance, oil resistance, salt water resistance, corrosion resistance, can prevent smoke, no dripping, and can be constructed by adding water and stirring on site, which is simple and convenient
Refractory mortar is suitable for plastering construction of internal and external walls of various brick-concrete structures, frame structures and shear wall structures, as well as basements, garages, unheated stairwells, corridors, fire passages and other public facilities with high fire protection requirements. Fire protection construction with building renovation works.
