Scope

Scope: This specification is formulated to ensure the advanced technology, reasonable design, energy conservation, and cost reduction of double-sided walls made of autoclaved aerated lightweight concrete, thereby improving economic and social benefits, ensuring project quality and safety, and preventing potential risks. This document applies to earthquake-resistant areas with a seismic intensity of 8 or lower, and is suitable for the design, construction, and acceptance of new, renovated, and expanded residential, public, and industrial buildings, including exterior and non-load-bearing interior walls. Main technical requirements: - The main materials of double-sided walls should have sufficient compressive and tensile strength to ensure the stability of the overall wall structure, meet the load-bearing requirements of building exterior walls, and comply with relevant provisions of current national standards. - Double-sided walls should meet fire protection requirements and comply with the provisions of the current national standard GB 50016. - Double-sided walls should be integratedly cast with lightweight aggregate concrete and comply with the current industry standard JGJ/T 12. - Special embedded parts, bolts, and window/door frames used in ALC double-sided walls should comply with the relevant provisions of the current national standards GB 50010 and GB 50017. - The waterproof sealant used for TW wall joints should be weather-resistant, compatible with concrete, and have low-temperature resistance, mold resistance, and water resistance. Its maximum expansion deformation, shear deformation performance, and other properties should meet design requirements. Other performance specifications should comply with relevant current standards. - ALC double-sided walls, connection structures, and accessories should be standardized and serialized, and should adopt the principle of fewer specifications and more combinations to meet the requirements of prefab
