Abstract

In modern construction, the problem of increasing the durability and reliability of concrete structures is becoming increasingly relevant. One of the promising areas is the creation of self-healing concretes with the properties of repairing microcracks during operation, which significantly extends the service life and reduces repair costs. An important aspect is the correct selection of components and technologies for their application, since the effectiveness of such materials depends not only on the introduction of special additives, but also on the consistency of the entire composition of the concrete mixture. As part of the development of an innovative product, self-healing concretes (SHC), in cooperation with LLC "ASTOR INVEST" and LLC "PENETRON UKRAINE" designed concrete with the additive "PENETRON ADMIX" was developed. The object of the study is the self-healing ability of the SHC type design concrete mixture. The following methods were used to evaluate the processes: determination of water permeability, phenolphthalein indication and structural analysis using an electron microscope. The beginning of recovery for the design composition occurs already on the 5th day, with a decrease in water permeability, and reaches zero after 17–22 days under pressure and without pressure. The control samples continued to pass water, despite the fact that the the water permeability also decreased for them Accordingly, the design composition with the additive has a higher degree of recovery. This crystal hydrates, which restore the microstructure of concrete. Structural analysis confirmed that the interaction of the components contributes to the restoration of the strength and tightness of concrete. The results obtained indicate that the creation of effective self-healing concretes requires a targeted approach to the selection of the composition and technology, which takes into account the interaction of all components of the system to achieve optimal characteristics and durability.
