Autoclaved aerated concrete has been widely used in recent years and has gradually begun to replace classical concrete systems. In this paper, the optimal compositions of D500 and D600 autoclaved aerated concrete, which are widely used as structural and insulation materials with low cement consumption, were determined using mathematical regression models. The data obtained from the experimental results were converted into a dataset in the Matlab program, and optimization was performed to achieve maximum strength and minimum cement consumption. This study identified the stages of the process for developing and adjusting the properties of an efficient autoclaved aerated concrete composition using a cement matrix with the addition of various microfillers. The amount of components and mineral and chemical additives in the composition of autoclaved aerated concrete was optimized. With the application of carbonate filler and microsilica, aerated concrete compositions with an average density of 500 and 600 kg/m3 and a strength of 1.1–2.24 MPa were developed, which correspond to the D500 brand in terms of density and D600 to B1–B2 in terms of strength class. As a result of this study, it was determined that despite a 16.4% decrease in cement consumption when various microfillers were added to the cement matrix, the compressive strength of the D600 brand aerated concrete at 7 days was 1.35 MPa, and at 28 days, it was 2.25 MPa. Since the prepared aerated concrete composition is more efficient than traditional porous concrete, it can be widely used in the production of lightweight structures and insulation blocks. This research supports the Sustainable Development Goals (SDGs), particularly Goal 9 (Industry, Innovation and Infrastructure), Goal 11 (Sustainable Cities and Communities), and Goal 12 (Responsible Consumption and Production), by promoting the development of resource-efficient and environmentally sustainable building materials.
