Abstract

The article considers the experience of mathematical modeling of the effect of a combination of various additives on the strength characteristics of a construction composite based on forest industry waste (sawdust concrete), compares the simulation results with the data of strength tests of composite samples, and provides an overview of existing methods of mathematical modeling experiments. The research was carried out according to the plan of a complete factorial experiment, with obtaining a regression polynomial from a complete cubic equation. The practical significance of the application of this experience will simplify the conduct of further research, thanks to a fairly accurate mathematical prediction of the results of strength tests of a number of images with the content of the studied additives within the previously studied values. Also, mathematical modeling of the study will allow you to analyze the results of past tests, determine the maximum and minimum values, identify erroneous and unreliable results.
