The article presents the results of research on optimizing the composition of fine-grained concrete reinforced with polypropylene fiber. Based on the implementation of an active experiment using the method of mathematical experiment planning, a mathematical model of the compressive strength limit of the modified cement stone was obtained. Through graphical-analytical analysis, the optimal values of formulation and technological parameters were determined, namely: the dosage of the superplasticizer MasterGlenium ACE 430 – 1.0% of the mass of the cement binder, the content of the mineral filler – ground zeolite-containing rock – 18% of the mass of the cement binder, and the content of polypropylene fiber FOX POLFIBER M12 – 0.4% of the mass of the cement binder.
