Refractory Mortar Fire Proof Mortar For Fire Brick Fixing High Temperature Resistant High Stength
Fire Proof Mortar
Fire Proof Mortaris referred to as soft clay. It is air setting refractory mortar a refractory clay with plasticity. The constituent minerals of high temperature mortar are mainly kaolinite and hydromica. Generally, refractory mortar mix contains Al2O322% ~ 30%, SiO 242% ~73%, and the refractoriness is 1580 ~ 1670 °C.
The refractory clay foam is softened in water and can be made into various shapes, and firebrick mortar is a raw material for making a refractory material, as a binder and in a hard refractory clay. According to the chemical composition (useful components, harmful components), physical properties (refractory degree, plasticity, loss on ignition, etc.
) of soft refractory clay, fireproof mortar can be divided into three grades: I, II, and III.
Application of Refractory Mortar:
Suitable for masonry clay bricks , high alumina bricks and any
other fire bricks
