Developing compositions and technologies for concrete production typically requires a complete cycle of activities—from theoretical modelling and laboratory trials to semi-industrial and industrial testing, followed by pilot-scale manufacturing. When the goal is to achieve specific target properties, discrepancies between laboratory and industrial outcomes are often observed due to differences in curing regimes, scale, and material variability. To address this, the present study proposes a method for introducing correction factors that allow laboratory data to be translated into reliable industrial performance indicators. Transition coefficients for operational quality control of non-autoclaved aerated concrete on ash and slag waste have been developed. It has been established that to predict the actual strength of industrial samples based on the results of tests in 1 day with heat treatment, a coefficient of 1.684 is used, and for density, 0.851. When using the results of tests in 7 days without heat treatment, these coefficients are 1.917 for strength and 0.838 for density, respectively. These coefficients allow for minimising time and resources during the transition to industrial production. Copyright
