abstract = {This study investigates the effectiveness of ethyl silicate in enhancing the durability of extruded bricks subjected to weathering used by sodium sulphate. Four groups of samples were analyzed and compared: unaltered bricks (F1), salt-weathered bricks (F2), consolidated salt-weathered bricks (F3), and re-weathered consolidated bricks (F4). Chemical and mineralogical changes were evaluated using X-ray fluorescence, Fourier-transform infrared spectroscopy, μRaman spectroscopy, and powder X-ray diffraction. Hydric tests and ultrasound measurements assessed changes in the pore structure and mechanical properties. Colour  measurements quantified aesthetic alterations. Mechanical tests evaluated strength, hardness and fatigue resistance. A
computational model was also developed to predict long-term behaviour. Results indicate that ethyl silicate treatment significantly enhances weathered brick durability, with consolidated saltweathered samples showing improved mechanical properties and reduced salt damage. However, the re-weathering process revealed some limitations in providing long-term protection. This
research offers novelty insights into ethyl silicate consolidation for preserving bricks under conditions of salt weathering.},
