magnesia brick as well.

can be used for laying on blast furnace lining.

3. Fire clay brick use local materials, cheap price, durable, and fire prevention, heat insulation, sound insulation and absorption of moisture, widely used in civil instruction engineering, waste brick

bat also can make concrete aggregate.

4. Fly ash fire clay brick with fly ash as main raw material, mixed with coal gangue powder or clay and cementation material, going through the ingredients, molding, drying and calcination
