This article presents the results of a study on the influence of one component of a newly developed modifying additive (specifically, granite dust) on the strength properties of concrete. The comprehensive study included standardized tests of beam samples for flexural and compressive strength. The research was conducted with varying concentrations of granite in the concrete mix: 1%, 2%, 3%, and 4%. The study results yielded curves illustrating changes in concrete strength relative to the concentration of granite added to the mix. The resulting curve of this relationship indicated that the optimal concentration of granite in concrete is 2%, at which the maximum sample strength was observed. With further increases in granite concentration, a decrease in strength was noted, both in compressive and flexural strength indicators.
