           The paper studies the impact of crystallization parameters and water chemical composition on strength and tribological characteristics of ice formed by artificial and natural cold. The results of experimental researches certify the possibility of increasing ice strength properties by introduction of microdoses of high molecular modifying compounds into freezable water solution forming ice. Experiments proved the utility of combination of ice modification and reinforcement using up-to-date high-strength fibers. Criteria of choice of chemical compounds and reinforcing materials in terms of conjugation of physical and adhesive features are developed. The paper examines features of the obtained ice structure depending on freezing rate, concentration, modifying compounds and reinforcing elements types as well as gives the examples of testing of ice covering technologies in sports facilities; the perspectives of their application in arctic regions were estimated.
