Abstract: The results of the study on the physical and mechanical characteristics of fine-grained fibre-reinforced concretes with multifunctional modifying additives are given. The influence of modifying additives and dispersed fibres on the water demand of fibre-reinforced concrete mixtures, the density in normal humidity conditions, and the limits of flexural and compressive strength of cement composites was established. The analysis of deformation diagrams for three-point bending of modified fine-grained fibre reinforced concretes was performed. According to the results of the study, compositions characterised by increased fracture toughness and the highest values of strength properties were identified.
