Autoclaved Aerated Concrete

AAC (Autoclaved Aerated Concrete) wall blocks are lightweight, mineral-based building elements produced using a mixture of sand, cement, lime, gypsum, water, and aluminum paste. During the production process, chemical reactions create millions of air pores, resulting in natural insulation and reduced weight. This EPD is a representative EPD for AAC wall blocks and covers the product classes G2/350, G2/400, and G3/500. Within the assessed product group, densities range from a minimum of 350 kg/m³ to a maximum of 450 kg/ m³. For modelling in this study, a product with a density of 350 kg/m³ was selected as the declared product. This selection does not imply that the 350 kg/m³ product represents the other classes; it is simply the specific product modelled within the scope of the representative EPD.

Applications:

AAC wall blocks are used in residential, commercial, and industrial buildings. Typical applications include interior and exterior walls, infill walls in frame structures, and non-load-bearing partition walls.

Advantages:

Excellent thermal insulation without the need for additional materials

A1-class non-combustible material, resistant up to 1000 °C

High sound insulation

Lightweight and easy to cut, shape, and install

Reduces dead load, mortar, and plaster usage

Speeds up wall construction and lowers labor costs

Environmentally friendly and recyclable
