Original language description
The properties of most silicate base produced structural materials depend to a large extent on their porosity and, at the same time, on the actual gas pocket filling with water or water vapour. The quality of a construction material used in a particularstructure is subject to degradation in the course of its long-time utilization. The changes in propersties that the structural materials undergo during this period are extremely difficult to keep track of and the same holds for the assessment of the cauuses for their degradation. One of objective methods allowing to quantify the instantaneous status of the porous structure of building elements is the surface layer air permeability determination method. It is a new, not-destructive method, applicable both in the laboratory and "in site". The surface layer permeability of a structural materials depends on the gas pocket overall volume in and distribution over the layer under test, on the humidity and the geometrical and physical parameter
