Introduction Under the ongoing martial law in Ukraine, amid profound socio-economic challenges, the need to build reliable, durable structures for civil and critical infrastructure has become particularly urgent. The restoration of destroyed buildings, the strengthening of strategic structures and the construction of new ones require the use of building materials with increased performance characteristics. One of the most effective technological approaches in this direction is the dispersed reinforcement of concrete with reinforcing fibers (Kos et al. (2024); Kroviakov (2025); Borysiuk et al. (2021)). To increase the air-entrainment content in cement concrete mixes, reduce their segregation, decrease the shrinkage of pavement concrete, as well as to improve crack resistance, impact resistance, tensile and compressive strength, frost resistance, and corrosion resistance, fiber is added to the composition of pavement Abstract The main criterion for assessing the durability of concrete under aggressive media is the change in its compressive strength. Experimental results demonstrated that the use of combined fiber reinforcement — consisting of both steel and polypropylene fibers — significantly enhances the resistance of concrete to aggressive environments. Among the tested media, the strongest effect on concrete properties was observed in hydrochloric acid, followed by kerosene and finally water, which had the least influence. After 12 months of exposure, the decrease in compressive strength was most pronounced in acidic conditions: the resistance coefficient dropped to 0.54 for fiber-reinforced concrete and to 0.5 for ordinary concrete. Under kerosene exposure, the loss of strength was moderate, while in water, the samples retained the highest strength. The obtained results confirm the feasibility of using fiber-reinforced concrete as an effective material for rigid road pavements and other structures subjected to intensive loading and dynamic effects.
