    Abstract. An assessment of the effectiveness of fiber reinforcement in terms of neutralizing the destructive effects of the environment on hardening concrete at an early age is presented. The results of a study of indirect indicators of durability (water absorption, strength) of hardening high-strength concretes by testing for weather resistance are considered. Changes in the indicated parameters of concrete and fiber-reinforced concrete samples during accelerated tests simulating the impact of the environment on their structure and properties at an early age are presented. At the same time, samples of all compositions were subjected to alternate moistening and drying when they reached the age of three and seven days under conditions of normal hardening. It is established that the introduction of non-metallic fibers into the composition of high-strength concretes, due to the reinforcing and modifying effects, makes it possible to improve the parameters of the structure and increase the strength of concrete, which implies an increase in the durability and operational reliability of the structure as a whole.
