本来想找出之前看过的用聚氨酯发泡做粘接剂的一个砌体结构的案例，可惜没找到。想表达的内容是，砌体结构是可以粘在一起的，不是用砂浆。

可能和国内规范有冲突（我记得国内砌体结构要回弹灰缝砂浆强度的）

In Eastern and Western Europe, many AAC plants successfully supply both AAC blocks and AAC panels. Japan until today, remains a 100% reinforced elements market (fig. 5). Since 2002, reinforced element production was further perfected by the Dutch and nowadays Aircrete Europe’s technology allows manufacturing complete prefab AAC building solutions. Taking into consideration fast, economic and structural building with AAC panels, many countries today are looking for ways to introduce complete AAC building solutions in their local construction markets.

在东欧和西欧，许多AAC工厂成功地提供了AAC模块和AAC面板。直到今天，日本仍然是一个100%增强元件市场(图5)。自2002年以来，荷兰进一步完善了增强元件的生产，如今Aircrete欧洲公司的技术允许制造完整的预制AAC建筑解决方案。考虑到快速、经济和结构建筑与AAC面板，许多国家今天正在寻找方法，以介绍完整的AAC建设解决方案在其当地建筑市场。

Mergers & Acquisitions

Mergers and acquisitions wave of the 1990s has had a crucial impact on the world of AAC as we know it today. In the period between early 1990s and early 2000s, ownership of technologies, plants and brand names became disoriented. Plants, patents, technologies and patents of Durox, Ytong and Hebel ended up under one roof and named Xella. At one point,Hebel and Durox products were produced under the brand name Ytong, as all three brand names were unified under the name Ytong. In 2001, a range of factories were closed under the premise of overcapacity.Many AAC technology specialists lost their jobs. Hebel took the biggest hit as their main base in Emmering, Germany was closed, and some Hebel facilities were liquidated, stating that production  costs became too high. The market of architects, builders and especially the end consumers could not understand the disappearance of the well-known brands. Following this, the brand “Hebel” was reinstated as a brand for the reinforced products, while Ytong remained a brand for blocks. Furthermore, not a single Durox plant was closed throughout AAC’s history and AAC is produced until now in the remaining plants as well as the original Durox based plants.The period was an exodus of know-how in AAC world and many licensees had to fi nd their own way in the world of AAC.

上世纪90年代的并购浪潮对我们今天所熟知的AAC行业产生了至关重要的影响。在20世纪90年代初至21世纪初，技术、工厂和品牌的所有权变得混乱。Durox、Ytong和Hebel的植物、专利、技术和专利被集中在一个屋檐下，命名为Xella。Hebel和Durox的产品一度以Ytong品牌生产，因为这三个品牌都统一在Ytong名下。2001年，在产能过剩的前提下，许多工厂被关闭。许多AAC技术专家失去了工作。赫贝尔受到的打击最大，因为他们的主要基地在埃默林，德国被关闭，一些赫贝尔的设施被清算，声称生产成本变得太高。建筑师、建筑商，尤其是终端消费者无法理解知名品牌的消失。随后，“赫贝尔”品牌被恢复为加固产品的品牌，而“逸通”则保留了几个街区的品牌。此外，在整个AAC的历史中，没有一家Durox工厂被关闭，直到现在，在剩余的工厂和最初的Durox工厂都生产AAC。这一时期AAC领域的技术人才大量流失，许多获得执照的人不得不在AAC领域找到自己的路。
