Invented in the mid-1920s by Swedish architect Dr. Johan Axel Eriksson, AAC is manufactured by combining quartz sand, calcined gypsum, lime, cement, water, and an expansion agent (typically aluminum powder). The mixture is poured into molds, where the aluminum reacts to create hydrogen gas, causing the material to expand to about five times its original volume. After a pre-curing period, the \u201ccake\u201d is cut into precise blocks or panels and then cured in an autoclave (a high-pressure steam chamber) for approximately 12 hours. This process results in a material with a unique cellular structure that offers excellent thermal insulation, sound absorption, and workability. AAC blocks are widely used in residential, commercial, and industrial construction globally, particularly in regions requiring energy-efficient and fire-resistant building solutions.<\/p>\n<h2 id=\"toc-ef49c502fd13c49da9311ea5109d7504\">Global Top 10 Suppliers and Factories of AAC Blocks<\/h2>\n<p>The global AAC market is dominated by established manufacturers with strong production capacities and distribution networks.

Blocks with density 700 kg\/m\u00b3 typically achieve 8\u201310 N\/mm\u00b2.<\/li>\n<li><strong>Q: How to import AAC blocks from China to my country?<\/strong> A: You need to find a supplier, agree on Incoterms (FOB or CIF), arrange customs clearance, and check local building codes for AAC acceptance.<\/li>\n<li><strong>Q: Are AAC blocks fire-resistant?<\/strong> A: Yes, AAC blocks are non-combustible and can withstand temperatures up to 1200\u00b0C for 4\u20136 hours, depending on thickness.<\/li>\n<li><strong>Q: What is the difference between AAC and ALC blocks?<\/strong> A: AAC is autoclaved aerated concrete; ALC (autoclaved lightweight concrete) is a similar product but often includes steel reinforcement for panels. The terms are sometimes used interchangeably.<\/li>\n<\/ol>\n<h2 id=\"toc-d52bf7c8af23b99b17fcee3624eccdc3\">Zolldaten und Zolltarife<\/h2>\n<p>Import duties on AAC blocks vary by country.

Differences from Large Factories<\/h2>\n<p>Small and medium-sized AAC factories (annual capacity 50,000\u2013200,000 m\u00b3) offer distinct advantages over large-scale plants. They typically provide more flexible MOQs (as low as 10 m\u00b3), faster turnaround times (10\u201315 days), and personalized customer service. Many medium factories are family-owned and prioritize quality over volume, often using premium raw materials. In contrast, large factories (500,000+ m\u00b3) focus on standardization, lower unit costs, and automated production lines, but may require large MOQs and longer lead times. For niche projects or first-time importers, medium factories reduce financial risk and allow for product customization. However, large factories offer better consistency for mega-projects and have more robust export documentation.<\/p>\n<h2 id=\"toc-7adac5807387e0592234129f55dcdd6b\">2026 News Roundup from Major Media Sources<\/h2>\n<p>The following news items are compiled from reputable industry publications and news outlets as of early 2026.<\/p>\n<ul>\n<li><strong>\u201cGlobal AAC Market to Reach $25 Billion by 2027\u201d<\/strong> \u2014 <em>Global Construction Review<\/em>, January 2026.
