Currently in the UK, aircrete, also known as Autoclaved Aerated Concrete, masonry units are usually produced with a minimum declared compressive strength of 2.9 N/mm2 (measured to EN 772-1) and a minimum density of 400 kg/m3. However, newly introduced European Standards allow the use of lower strength and with this it is possible to produce lower density products, such as low-density aircrete with a minimum declared compressive strength of 2.0 N/mm2 and a density of 350 kg/m3. This paper provides details of an extensive investigation to assess key physical properties such as moisture properties, freeze/thaw resistance, thermal performance, combustibility and flanking sound performance of low-density aicrete products The results show that key physical properties of low-density aircrete were comparable to conventional aircrete products.
