Yes, AAC (Autoclaved Aerated Concrete) blocks can be used for load-bearing walls, as they have high compressive strength between 3 to 4 N/mm² and are lighter in weight, making them a popular choice for construction projects. However, it is important to note that the design of the wall and the thickness of the blocks should be carefully considered to ensure that they can support the weight of the structure.
The strength of the wall will also depend on factors such as the mortar used, the quality of construction, and the presence of any additional reinforcements, such as steel bars. Therefore, it is recommended to consult with a structural engineer or a qualified professional before using AAC blocks for load-bearing walls to ensure that the design is appropriate and meets the required safety standards.
