Advantages and Implications of Low Density Aircrete Products for the Construction Industry

Low Density Aircrete (Density ≤ 450 kg/m3 , compressive strength ≤ 3 N/mm2 ) has been used extensively for the construction of dwellings in many parts of Europe. In the UK, however, lack of availability has restricted the use of Low Density Aircrete. Recent developments in Eurocode 6 and the supporting CEN TC 125 standards require adjust ment to the UK design procedures, allowing greater utilisation of Low Density High Performance Aircrete. The material has considerable advantages, which include its economical, mechanical and physical properties. It is usually manufactured using pulverised fuel ash, which is an industrial by-product. The potential for using Low Density Aircrete for the UK and indeed global construction industry is therefore highly promising with substantial economic and environmental benefits. Furthermore, calculations show the termal insulating (shielding for hot climates) properties of this material. Keywords: Low Density Aircrete, Sustainable Masonry.
