Determination the durability of concrete structures based on the migration test of chloride ions
Języki publikacji
Abstrakty
Trwałość konstrukcji żelbetowych oszacowano, wyznaczając czas do momentu wystąpienia zagrożenia zbrojenia korozją. Okres ten określono według rozwiązania równania dyfuzji z uwzględnieniem doświadczalnie uzyskanej wartości współczynnika dyfuzji na podstawie badań migracji chlorków w polu elektrycznym. Badano zarówno beton zwykły, jak i wysokowartościowy.
The durability of concrete structures was estimated by calculating the time until the occurrence of a risk of reinforcement corrosion. This period was determinated in accordance to solution of diffusion’s equation with the use of the value diffusions coefficient obtained in the migration test of chloride ions. The both ordinary and high strength concrete was tested.
