Abstract

Purpose. To study various additives of a domestic production and to estimate expediency of their use for products of transport construction. Methodology. The study was conducted by introducing a superplasticizer and active mineral additives Findings. The complex additive should include effective superplasticizing admix, as well as additives which operate stiffening and hardening kinetics, air retaining substances and defoaming agents, dispersion and fine-dispersion mineral fillers. In recent years organo-mineral modifiers such as superplasticizer - an active mineral additive (microsilica, metakaolin, ash) obtained a wide circulation. Originality. The impact of various additives on the concrete quality is studied. It is found out that the complex additive PLKP deserves the special attention because it allows producing a concrete of very high durabilityand is recommended for use in railroad ties. Thus, the introduction of additives in the concrete can significantly increase the durability and reliability of concrete products. Practical value. Results of the research can be used to improve the reliability and durability of concrete structures. This calls for further researches on the selection of the concrete mixture with complex additive PLKP, as well as adding the active mineral components.
