Advantages and disadvantages of clay brick

Advantages :

① clay brick at high temperatures is weakly acidic, alkaline slag erosion resistance to a bit weak, but with Al2O3 content increased and enhanced. Thermal stability than the refractory brick, magnesia brick as well.
②After the blast of acceptable quality clay dried vacuum impregnation process phosphoric acid, phosphoric acid impregnated low-temperature firing of secondary products, it can be used for masonry lining blast furnace body portion.
③Brick from local materials, cheap, durable, as well as fire protection, thermal insulation, sound insulation, moisture absorption, etc., used in a wide range of engineering works. Waste and scrap refractory bricks can be made of concrete aggregate.
④Fly ash brick with fly ash as the main raw material, mixed with coal gangue cement or clay refractory materials, ingredients, forming, drying and roasting can make full use of industrial waste, saving fuel.

Disadvantages:

① self-important, clay brick masonry wall material by weight than other weight is relatively large, so that the structure needs to withstand greater weight, construction cost increases.
② poor sound insulation, sound propagation to. clay due to its porosity is small, there is no sound isolation, sound decibel decrease is small, and other masonry materials such as now adopted more concrete aerated block its large porosity, noise effect is obvious.

③ environmental damage to large, due mainly clay soil excavation by sintering, and therefore damage to soil and vegetation damage, resulting in soil erosion, bad environment has been severely damaged.
