Autoclaved Aerated Concrete

Aerated autoclave concrete (AAC) is the first preference of contemporary world as a building material, providing buildings with multifarious contributions.

• It is a porous and lightweight building material.

• In terms of volume, 70-80% of it consists of pores.

• AAC is a massive material with low density.

• Furthermore, it is the masonry wall material with the lowest heat conductivity.

STT TÜRK GAZBETON having one of the widest product ranges in AAC sector in Türkiye, produces three main products called block products, reinforced products and insulation plates. Block products are load bearing and/or non-load bearing blocks having with or without tongue-groove profiles, lightweight hollow blocks, U-blocks and insulation plates. Reinforced products are vertical and horizontal wall panels, partition walls, lintels and jambs. AAC is a non-flammable A1 class product and has high thermal insulation properties.

The product investigated in this EPD is STT TÜRK GAZBETON's autoclaved aerated concrete produced at companies two production plants located at Kırıkkale and Tekirdağ provinces in Türkiye. Manufacturer has a range of AAC production between 350 - 600 kg/m3. The chosen dry weight of the product for this EPD is 400 kg/m3. Thus, life cycle assessment analyses for this specific weight have been conducted for two production sides. Types of materials and the production routes are the same between the two production sites. There are only small changes in material quantities. According to the LCA analysis, there is less than 10% environmental performance difference between two sites. Thus, results in this EPD covers both sites.
