Red brick is made of clay, shale, coal gangue and other raw materials; Blue brick is a kind of sintered brick. The main raw material is clay, which is extruded after mixing with water. Red bricks should be fired at a high temperature above 900 degrees; Blue bricks need a high temperature of 1000 degrees to be successfully fired. After the red brick is fired, it only needs to be put into the cellar to cool naturally; Only when water is poured into the cellar when it is cooled can blue bricks be made. Blue brick is superior to red brick in oxidation resistance, hydration and atmospheric erosion.
