At the present stage, materials used within the framework of low-carbon technology are becoming increasingly in demand. The purpose of the study was to identify and study the analytical dependencies of technological parameters and aspects of the preparation of foam concrete depending on the concentration of foaming agents (surfactants) at various points in the formation of the capillary-porous structure of foam concrete as low-carbon technology. The law of acting masses was adopted as the main basis for assessing the kinetics of interaction of light concrete components with surfactants. This thesis is interpreted taking into account the fact that the ratios between the concentrations of reagents and their products at a discrete time are considered to be constant. The questions of estimating the speed of the processes are formalized. In contrast to the traditional approach, the material is considered from the standpoint of implementing calculations using analytical algorithms for solving direct and inverse kinetic problems. The issues of effective use are considered. The literature on technical kinetics practically does not address the issues of specific practical implementation of kinetic calculations. Dynamic models for estimating and controlling the kinetics of the formation of pore structures have been developed. The practical use of the developed dynamic models makes it possible to evaluate and promptly adjust the parameters of foam concrete of the formation of capillary-porous structures of foam concrete as low-carbon technology
