Facing bricks are considered one of the oldest and most reliable materials for construction. It not only decorates buildings, but also protects them from various negative external factors. The main secret ingredient of facing bricks is natural clay. However, its production process and ingredients can vary. Let's take a closer look at what materials bricks are made of.
1. Clay
Clay is the main component in the production of bricks. Depending on the fertility of the clay and its location, bricks can have different shades - from light yellow to dark red.
2. Sand
Sand is added to the clay to improve its plasticity and prevent it from rolling off during firing. This allows for more uniform and stronger bricks.
3. Lime
Lime is added to clay to reduce its shrinkage during drying and firing. This helps prevent cracks in the finished brick.
4. Iron
The addition of small amounts of iron oxide can change the color of the finished brick, giving it a red or brownish tint.
5. Manganese and barium
These elements can be used to give the brick additional shades, from pink to purple.
6. Water
Water is added to the mixture to give the clay the desired consistency, which helps to form bricks.
7. Various additives
Sometimes various additives are added to the clay to improve the quality of the product, increase its strength, fire resistance or frost resistance.
Production process of facing bricks
From the moment the right clay is selected to the moment the bricks are fired, the entire production process requires great attention to detail. After all the components are added, the clay goes through several processing stages, including grinding, mixing, molding, drying, and firing.
With the help of modern technology, manufacturers can vary the texture, color, and shape of bricks to suit different architectural styles and personal preferences of consumers.
Facing bricks are a natural and environmentally friendly material made from clay and several other components. The choice of clay, as well as additional materials, affects the color, texture and strength of the final product. It is important to choose facing bricks from reliable manufacturers who adhere to quality standards and use high-quality raw materials for their production.
