REVIEW ON APPLICATION OF AERATED CONCRETE IN LIGHTWEIGHT CONCRETE SLABS

Abstract

A building constitutes of slab structures on a big volume for about 40 to 60% of its total self-weight. Using a lightweight concrete alternate for the existing conventional concrete mix will create a huge impact in reducing the self-weight of the structure thus improving its efficiency without affecting its load bearing capacity. Aerated concrete is one such good alternate for the conventional concrete mix, which is lighter but possess comparable compressive strength as that of the normal concrete. In most cases, the aerated concrete is applied in the form of precast Autoclaved Aerated Concrete blocks which helps in reducing the cost and construction time of the structure. This article reviews on various journals that have discussed on application of Autoclaved Aerated Concrete (AAC) in creating lightweight concrete slabs and also the efficiency of sandwich concrete slabs, which have been presented by casting slab, performing physical tests and software analysis.
