dcterms:description
Problems of the relation between concrete durability and life cycle of the structures are topical at present. Durability of concrete is limited by its quality, especially by a state of its surface layer. This layer is a point of entry for penetrating environmental effects via concrete to reinforcement. Cracks origin in a porous structure of concrete even in early stage of setting and hardening, subsequent cracks develop in the stage of maturation and substantial ones develop in the course of operation of a structure together with the of temperature changes effects. The very problem is an absence of objective testing methods that would detect the faults in concrete. Development of non-destructive electro-acoustic diagnostic method in the last years made great progress and so it is possible to localize non-homogeneity or cracks in concrete using either ultrasonic or resonance method. These methods can be combined with the ones describing a state of porous structure of covercrete. One of these methods is a method of air permeability. Based on experimental tests either on samples or cores carried out in a laboratory and in situ, a recommendation for protection improvement both of RC and prestressed structures will be elaborated. The recommendation will serve for a design of %22Recommendation for protection improvement of both RC and prestressed structures%22. This recommendation is appointed for the designers and contractors at realisation of the engineering works. O trvanlivosti betonu rozhoduje stav povrchové vrstvy. Rychlost průniku agres. plynů nebo vody závisí na její struktuře. Stav struktury lze popsat zkouškou její propustnosti a NDT elektroakustickými metodami. Výsledky prací budou zpracovány pro Doporučení ke zvýšení ochrany ŽB a PB konstrukcí.
