This study evaluates sodium sulfonate as a structuring surfactant for non-autoclaved aerated concrete to stabilize pore formation and improve performance. A laboratory dosage series (0-0.25% by cement mass, water-to-cement ratio 0.45) and a pilot D700 production verification (GB1-GB4) were performed. At 28 days, the reference mixture reached 1.5-2.0 MPa, while 0.10-0.15% sodium sulfonate increased strength to 2.3-2.7 MPa; higher dosages reduced strength and impaired pore stability. In the pilot series, average density ranged from 610 to 740 kg/m3 and compressive strength from 2.0 to 2.5 MPa, with GB3 showing the best strength-to-density balance (SQC 0.034). Abrasion improved from 0.84 to 0.71 g/cm2. The additive improved plasticity and pore uniformity. Overall, 0.10-0.15% is recommended for practical production with minimal process complexity.
