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.
