The aim of this dissertation work is to study the utility of Autoclaved Aerated Concrete Blocks (AAC), which is a well known light weighted concrete blocks with many other advantages over traditional concrete blocks, like sound insulation, thermal insulation and many more. Brief of all the materials used in making of AAC blocks were discussed in the dissertation. Along with the material, processes involved in the making of AAC blocks were explained. For the study, AAC blocks were designed and then some preliminary estimation of physical and elastic properties was taken into account. The various parameters for AAC blocks, table moulded bricks (TMB), wire cut bricks (WCB), solid concrete blocks of size 100 mm, 150 mm and 200 (SCB -100, SCB-150 and SCB-200, respectively), hollow concrete block of size 150 mm (HCB-100) and stabilized mud block with 8% cement and size 143 mm (SMB-143) were compared to establish the feasibility of AAC blocks over all other variants available in market. Later, the studies were extended to obtain the strength and elastic properties of AAC masonry. Here, the focus was compressive strength of prisms and wallettes, flexural strength and shear bond strength.
