Ytong corner blocks are used for the construction of vertical earthquake-resistant reinforced concrete reinforcement belts at the corners of external walls, at the joints between external and internal load-bearing or connecting walls, as well as in long walls (l > 5.0 m) that do not have transverse load-bearing walls. These elements enable the creation of these reinforcement belts without the need for external formwork. Ytong corner blocks are an indispensable part of the Ytong construction system. With optimal use of reinforcement and concrete, they provide a strong and safe structure, and are quick and easy to install.
