THE PROPERTIES OF FIRE CLAY BRICKS

Fire clay bricks are https://cheapfirebricks.com/ which are made of clay clinker as aggregate, refractory clay as binder and Al2O3 content is generally above 40% in China.

Fire clay bricks, also known as sintered bricks, are artificial small blocks for construction. Fire clay bricks are made of clay (including shale, coal gangue and other powders), processed by mud mixing, shaping, drying, sintering and matching.

They are used inconstruction of artificial small piece of material, is one of the world's oldest building materials. With clay (such as shale, coal gangue powder) as themain raw material pass through sludge processing, molding, drying and roasting completed. The main raw material of fire clay brick is nature or sandy clay, its main chemical composition is SiO2, Al2O3, Fe2O3 and crystallization water, because of the different geological formation conditions, may also contain a small amount of alkali metal and alkaline earthmetal oxides. The production technology of fire clay brick mainly includes soil, mud, blocking, drying, roasting, etc.

Due to the difference in the chemical composition and production process of https://cheapfirebricks.com/fire-clay-bricks/, its properties fluctuate over a wide range. Generally speaking, fire clay bricks possess the following advantages:

1.The blast furnace fire clay brick of quality qualification goes through dryingtreatment, vacuum impregnation phosphate, secondary low temperature firing ofphosphate impregnation products, can be used for laying on blast furnacelining.

2.Fire clay brick shows weakacid under high temperature, alkaline slag erosion resistance is a bitpoor, but enhanced with Al2O3 content increase, and the thermal stability thansilica brick, magnesia brick as well.

3.Fire clay brick use local materials, cheap price, durable, and fire prevention,heat insulation, sound insulation and absorption of moisture, widely used incivil instruction engineering, waste brick bat also can make concreteaggregate.
