The difference between clay brick and clay brick

There are also two kinds of clay bricks, 1. They are clay bricks for ordinary buildings.

2. It is a clay brick on refractory.

Clay bricks for ordinary buildings are red bricks made of a kind of clay. (that is, red bricks used in old houses) Because a lot of original resources are used, it is very polluted when fired, so it has been banned in some cities now.

The so-called cement brick is the use of fly ash, coal cinder, coal gangue, tailings, chemical slag or natural sand, beach mud and so on. (one or more of the above raw materials) is the main raw material. Generally speaking, a new wall material made of cement as accelerator without high temperature calcination is called cement brick.

Cement bricks are light in weight and high in strength, and do not need to be fired. The use of power plant pollutant fly ash is environmentally friendly and has been widely promoted in China. The only disadvantage of this kind of block is that it is not as good as red brick when combined with plastering mortar, which is easy to cause cracks in the wall and affect the appearance.
