Abstract: The article presents the results of studies on the influence of various additives on the water resistance of concrete, optimization was carried out, optimal values of additives were found, the microstructure of filled cement stone was also studied using X-ray phase analysis and electron microscopy. It follows from the X-ray phase study that the introduction of the superplasticizer additive reduces the content of portlandite in cement stone, which correlates with the results of thermal analysis, the results of the microstructure of cement stone modified by the introduction of polycarboxylate superplasticizer are represented by gel-like highly basic hydrosilicate phases, which is confirmed by the data of the X-ray microanalyzer.
Key words: cement, silica, polycarboxylate, superplasticizer, hydrophobizer, cement stone, modifying hydrophobizer, concrete, X-ray phase analysis, microstructure.
