A Comparative Study on Conventional Clay Bricks and Autoclaved Aerated Concrete Blocks

Abstract

In India, traditional clay brick is the most common filler material used in building. The materials used in construction have a significant influence on both the constructed environment and the project’s ultimate cost. Autoclaved Aerated Concrete (AAC) has recently emerged as a viable alternative to clay and fly ash bricks. In this work, a comparison of clay bricks and AAC blocks is explored. Although AAC blocks have been utilised in building since 1924, they now account for just 16-18% of all construction in India. AAC blocks have desirable mechanical qualities in proportion to their low bulk density, improved thermal and acoustic properties, light weight, and ease of installation, making them an obvious alternative to replace traditional clay bricks. The purpose of this study is to demonstrate the potential of AAC blocks as an infill material to replace clay bricks and to encourage its usage in construction to create more energy efficient and sustainable structures. AAC blocks’ potential as an infill material in hilly areas is discussed.
