The article presents the results of scientific research on the influence of polypropylene fiber FOX POLFIBER M12 BASF company (Germany) on the structure formation and properties of fine-grained fiber-reinforced concrete and determining the conditions and rules for its effective use in the manufacture of critical structures buildings and structures for housing, civil and transport purposes. The results of the experimental studies reveal the operating features of the FOX POLFIBER M12 polypropylene fiber in building structures and its influence on the rete . The article presents the results of experimental studies on the study of the kinetics of strength gain in the early stages of hardening of cement paste and the peculiarities of the formation of the microstructure of cement stone. It was revealed that an increase in the density of fine-grained fiber-reinforced concrete is caused by a decrease in mixing water consumption and compaction of the composite structure due to the formation of an additional amount of low-basic substances hydrosilicates . The obtained research results make it possible to significantly expand the scope of application of modified fine-grained concrete with polypropylene fiber FOX POLFIBER M12.
