The article presents the results of a study of concrete used for the production of driven piles, arranged in aggressive soil conditions. The technical solution was achieved by including polymer components in the concrete composition that improve the hydrophobic properties of concrete. A significant effect of the use of the additive is achieved when the technological regime of pile production is changed by the inclusion of heat-moisture treatment (HMT) in production. This makes it possible to use the maximum resource of the additive (according to the curing time of the polymer and concrete), significantly improving the physical and mechanical characteristics of the pile. For comparison, laboratory tests of prototypes were carried out with and without additives, with and without heat-moisture treatment. Laboratory investigations included the effect of the additive and production technology on the change in strength characteristics, water absorption capacity, frost resistance of concrete, and its resistance to aggressive environments. The results of laboratory measurements showed high values of the compared characteristics of samples with additives relative to traditional samples without additives. An additional effect is a reduction in construction time due to a reduction in the production time of piles by using HMT. The results of the study confirmed the effectiveness of using the additive in combination with heat-moisture treatment, therefore, the proposed concrete composition and production technology can be recommended for the manufacture of piles in aggressive soil conditions.
