| The study examined the effectiveness evaluated the efficacy of stearic acid (SA) as a biodegradable modifier of commercial water repellents used to intended to protect concrete surfaces against from environmental degradation. Three silane- and siloxane-based water repellents (A1SA, A2SA, A3SA) were applied to vibro-pressed concrete paving stones, both unmodified and modified units in both their unmodified form and after modification with stearic acid. The durability and effectiveness of the coatings were assessed on the basis of performance of the treated surfaces were comprehensively assessed through a series of tests such as, water absorption, resistance to freezing and thawing cycles, salt crystallization, water vapor permeability and UV aging tests. The hydrophobic properties characteristics of the treated surfaces were analyzed by measuring the quantitatively evaluated through contact angle measurements and free surface energy, while microstructural changes were analyzed investegated using SEM/EDS, profilometry and XRD techniques. The results showed findings indicate that modification with SA significantly increases markedly enhances the hydrophobicity of the tested coatings, enabling a hydrophobic achieving contact angle of up to 143°, and significantly improves resistance to salt crystallization, withas evidenced by minimal mass loss (0.33–0.36%). Furthermore, UV aging causedresulted only a slight deteriorationmarginal degradation in hydrophobic properties. The useapplication of deep machine learning methods (ResNet50, DenseNet121), allowed for effectivefacilitated accurate classification of coating types and their degreeassessmentt of their degradation based on surface texture characteristics. The results confirmfindings substantiate that stearic acid is an effective and environmentally friendly additive, that improves the durability and hydrophobic properties of protective concrete coatings.significantly enhancing both the durability and hydrophobic performance of protective coatings applied to concrete substrates. |
