Are bricks considered stones? What about stones?


Bricks or clay bricks are burned at very low temperatures (around 900 ° C) compared to their fellow species. Since they have a small proportion of clay, which normally ensures compressive strength and a smooth surface, a more open-pored substance is created. These pores soak up water very quickly and therefore have to be additionally plastered or covered with certain materials so that they are protected from rain.

clinker On the other hand, they are fired at very high temperatures (approx. 1200 ° C) and have a larger proportion of clay so that the pores can close completely. This process is known as sintering. The result is not only smoother, but also more pressure-resistant, more stable and more resistant to the effects of the weather. For this reason, clinker bricks are often used as a second facade layer. In order to keep the joints relatively narrow, house builders often use facing bricks, which creates a tidier joint pattern - unlike a conventional brick wall.

The Perforated brick is a masonry brick, a distinction being made here between elongated brick and vertically perforated brick. The decisive factor is the load-bearing capacity of the two bricks, which is significantly higher in the vertically perforated brick than in the elongated brick. The vertically perforated brick is therefore also well suited as load-bearing masonry. The general percentage of holes in this type of brick is between 25 and 55 percent. Particularly noteworthy is the improved thermal conductivity of the perforated brick, which, however, depends on the number and size of the holes.

The difference between traditional bricks and Thermal bricks lies in the filling. While the former are made with holes or gaps, the holes in the thermal insulation bricks are filled with insulating material.
