Autoclaved Aerated Concrete (AAC),中文通常称为蒸压加气混凝土,是一种高性能的轻质多孔硅酸盐建筑材料。其核心制造工艺是将硅质材料(如石英砂、粉煤灰)、钙质材料(如水泥、石灰)、发气剂(常用铝粉)和水混合搅拌,注入模具。铝粉与碱性物质反应产生氢气,形成均匀分布的微小气孔结构,使浆料膨胀。随后,坯体经过切割成型,送入高压蒸汽釜(Autoclave)中,在高温(约180-200°C)和高压饱和蒸汽(约0.8-1.2MPa)条件下养护数小时,促使硅质与钙质材料充分进行水热合成反应,生成以托贝莫来石(Tobermorite)为主晶相的稳定高强度材料。

“Autoclaved Aerated Concrete”(简称AAC),中文译为蒸压加气混凝土,是一种轻质、多孔的建筑材料,具有环保、节能和高性能的特点。以下是详细解释:
基本概念
AAC是一种通过高压蒸汽养护工艺制成的多孔混凝土,属于新型绿色建材。其主要原料包括硅质材料(如粉煤灰、石英砂)、钙质材料(水泥、石灰)以及发气剂(铝粉)等,通过混合、浇注、预养、切割和蒸压养护等步骤制成。
核心工艺
轻质性
密度为400-800 kg/m³,仅为普通混凝土的1/5,黏土砖的1/3,可显著减轻建筑自重,适用于高层建筑填充墙或低层承重墙。
保温隔热
导热系数仅0.11-0.18 W/m·K,是传统砖石的1/4-1/5,适合寒冷或炎热地区建筑节能。
防火与隔音
耐火极限可达4小时以上,且多孔结构能有效吸收声波,隔音性能优异。
施工便捷
材料轻便且可切割,便于运输和现场安装,提升施工效率。
总结来说,AAC通过高压蒸汽工艺和加气技术实现了轻质与性能的平衡,是建筑领域可持续发展的关键材料之一。
