Burnt clay brick is a predominant construction material used in construction. As we also know that the brick manufacturing process involves CO 2 emissions which leads to produce global warming. Hence to overcome these issues we have to focus on saving our environment. To fulfill this objective, new construction materials can be used for construction. Recently AAC blocks were used commonly for building construction and it is a far better alternative material for construction. Therefore this paper discusses the review of Building Construction by using Autoclaved Aerated Concrete Block (AAC), Fly ash brick and Clay brick as Masonry Component.
