With the vigorous development of prefabricated buildings in China, the maturity of assembly technology, the matching of materials and the professionalism of construction have become the focus of attention. As the most important lightweight wall enclosure material, the sealant for autoclaved aerated concrete (AAC) wall plays a major role in the joint sealing of the wall. In this paper, on the analysis of related standards and the application characteristics of sealants, the requirements of sealant for AAC external wall are discussed and summarized. The requirements include good compatibility and adhesion with the substrate, low modulus and high displacement ability, environmental protection, good weather resistance and paint ability (when there is painting demand for the joints).
