The difference between blue brick and red brick

The difference between blue brick and red brick lies in the difference of raw materials and technology, which leads to the difference of color and performance.

Different raw materials for production

Blue bricks are mainly made of sludge and clay, and their raw materials contain iron, so blue bricks are dark green or dark gray. Red brick is mainly made of red clay, and its raw material does not contain iron, so it will appear red after being made at high temperature.

Different processes

In the process of making blue bricks, it is necessary to go through a high-temperature firing process, which can enhance their hardness and compressive properties. Red brick is fragile mainly through natural drying processes such as sun exposure and air drying, so it is suitable for building walls and masonry.

Different applications

Because of its excellent hardness and compressive properties, blue bricks are suitable for buildings in high pressure environment, such as bridges and foundations. Red brick is suitable for buildings with low pressure load, such as houses and building walls.

Expand knowledge:

Both blue bricks and red bricks have certain applications in architecture, but at the same time, with the development of modern industrial technology, a new material-cement brick has appeared. Compared with traditional bricks, cement bricks are not only more advanced in production technology and more advantageous in production cost, but also can be applied to more building environments, and become one of the most widely used bricks in the construction field at present.
