Water transport in surface layer of fair-face concrete

摘要

In the production of fair-face elements is very popular, but aesthetic quality needs to withstandrnits lifespan. In the case of non-protected concrete surface, any failure is much more pronounced. An importantrnparameter determining the durability of concrete is the quality of the surface layer, as it is directly exposed to thernenvironment. In terms of durability properties, it is worth to monitor the parameters of the surface layers, particularlyrnthe transport processes. The paper presents the selected experimental methods for evaluation the qualityrnof the surface layer of concrete aimed at monitoring the permeability of concrete, since concrete permeability isrna property uniquely affecting durability of concrete. These methods are complemented by experimental resultsrnand other traditional tests. These findings will serve to further optimization of the structure being created, thusrnensuring its better aesthetic and functional characteristics.
