Product description

Fireplace refractory mortar is 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 Al2O3 ≥ 22% ~ 30%, SiO 2 ≥ 42% ~73%, and the refractoriness is 1580 ~ 1670 °C. The refractory clay foam is softened in water and can be made into various shapes.

Fireplace refractory mortar has following performance:

1. Good plasticity and convenient construction;

2. High bonding strength and strong corrosion resistance;

3. High refractory resistance, up to 1650℃±50℃;

4. Good resistance to slag invasion;

5. , Good thermal peelability.
