Original Abstract

The correlation dependence found in the so-called accelerated test enables us to determine intervals of real time in the natural environment of 0.03% CO2 corresponding to the intervals of accelerated exposition in 98% CO2. It may be said that in the case of type A, type B, type C and type D coatings on higher-quality concretes, the coating would have to be renewed with an interval of maximum eight years.

Czech abstract

Korelační závislost sestavená na základě tzv. urychlené zkoušky na hloubku karbonatace nám umožní stanovit interval skutečné doby expozice betonu v přirozeném prostředí 0,03% CO2, která odpovídá intervalu urychlené expozice v prostředí 98% CO2. Můžeme konstatovat, že v případě disperzních nátěrů typu A, B, C a D použitých na betony vyšší kvality, bude zapotřebí obnova nátěru v intervalu max. 8 let.
