Today, there are a large number of programs (calculators) on the market for calculating concrete mixtures, proportions, and composition, all of which somehow calculate only traditional mixtures consisting of cement, sand, and crushed stone. Stocks of traditional raw materials are being depleted, while the amount of man-made raw materials is growing. In this regard, the additives of man-made raw materials in the composition of building mixes are increasing from year to year, which suggests that the need for them is in demand. Unfortunately, the composition of the construction mix with additives of man-made raw materials is still determined only manually, followed by calculating the mass of an ingredient, without taking into account the density of the material. In this regard, the relevance of the study lies in the need to automate the process of selecting a building mix with additives of man-made raw materials. Considering that the problem is not only practical, but also scientific, interest in it is quite high...
