A fine-grained concrete mix based on fine sand and modified with a complex three-component additive including metakaolin, a superplasticizer, and a hardening accelerator has been developed. The study was conducted using the Box-Behnken factorial design and mathematical modeling in the R environment. The obtained values of compressive strength, flexural strength, and average density exceed those of the control composition. The research results were analyzed for reliability, descriptive statistics were obtained, and their correlation analysis was performed. A quadratic regression model of compressive strength was constructed and three-dimensional surfaces for the studied response functions were visualized. It was established that the synergistic effect of the complex additive is due to matrix compaction, a decrease in the water-cement ratio, and acceleration of the hydration process. The results confirm the possibility of using fine-grained concrete modified with a complex additive for the manufacture of prefabricated and monolithic structures, additive technologies, and have the potential to reduce the carbon footprint.
