The reasons for the formation of a brown plaque on a light clinker brick for paving (white, light gray) during operation are studied. Tests of brick were conducted, its mineralogical composition was determined, the nature of the secondary color of the bricks and materials of the base when laying brick were studied. There are two reasons for the formation of plaque associated with laying bricks. The area on which clinker brick was laid was characterized by the level of mineralized groundwater close to the surface, and evaporation of moisture from the surface prevailed over its absorption by the soil in the warm season of the year. I.e., all dissolved in the ground water salts migrated to the surface of the bricks through well permeable sandy masonry joints between products. The base under the bricks contained ferruginous minerals, particularly hematite, when hydrating which the hydroxides of iron were formed. Hematite also reacted with sulphates in groundwater with the formation of ferric sulphates. This confirms the higher sulfur content in areas with plaque and the presence of a film similar to crystalline hydrates. The analysis of the studies conducted made it possible to develop recommendations for performance of paving works with clinker bricks, to develop measures for elimination of already available plaque. The results of the studies proved that the loss of the aesthetic appearance of the clinker bricks for paving was caused not due to poor quality of brick, but the imperfection of the technology of its laying.
