| The paper presented an investigation into the rheological and physical properties and durability of concrete treated with anticorrosive coatings. The primary materials utilized include organosilicon compounds, silanes, methacrylic resin (MR), and epoxy resin (ER) modified with stearic acid (STA) or methyl esters (ME). A total of ten different resins were developed. The fundamental characteristics of the coated concrete were assessed, including watertightness, water absorptivity, water vapor diffusion, frost and salt crystallization resistance. Following a curing period of 28 days, the concrete samples were coated with the newly formulated coatings. Notably, the concrete treated with ER2 + SA demonstrated the lowest water absorptivity (1.76%) among all samples tested. Following 50 freezing-thawing cycles, the concrete with epoxy resins showed minimal mass change, ranging from 0.01 to 0.2%, whereas the reference concrete samples experienced a mass change of 3.11%. The concrete with the new coatings exhibited excellent resistance to salt crystallization, in contrast to the reference concrete, which suffered a 15% weight loss. The findings suggest that ME and STA derivatives can effectively serve as coatings for concrete used in cooling towers |
