Owing to the increased population in developing country like India, the demand of sustainable building material is likewise increased to meet its excessive consumption. In the present study, non-autoclaved aerated geopolymer (NAAG) blocks were developed using industrial waste [fly ash, granulated blast furnace slag (GGBS)], foam and aerating agents with less concentration of alkaline solution (i.e. 1.5–4 M) and tested for their physio-mechanical properties. These NAAG blocks achieved up to 13.5 MPa compressive strength. Optimized samples were tested for thermal and durability related properties. Performance evaluation of NAAG blocks exhibited low thermal conductivity and durable nature as compared to the clay bricks. This developed NAAG block is proven to be a cost-effective and energy effective solution and can be used as building material. [ABSTRACT FROM AUTHOR]
