Concrete brick
Concrete brick stands for the following building materials:
- Concrete roof tiles , artificially formed shaped blocks for the production of sloping roofs.
- Hollow block , a large-format building block for walls made of concrete or lightweight concrete with air chambers perpendicular to the storage area, which are closed at the top.
- Formwork stone, an artificial stone for masonry that contains one or more vertical air chambers that are open upwards and downwards. The wall made of such stones is subsequently filled with concrete.
