The article focus on the evaluation of forecasting method concerning the durability of prefabricated floor HC-500 slabs in conditions of danger of chloride ions aggression taking into consideration values of diffusion coefficient of concrete taken directly from prefabricated slabs. Diffusion coefficient obtained on the basis of thermodynamic migration model and own research and recommended by draft of norms fib Model-Code 2006 and fib Model-Code 2010 coefficient value obtained on the basis of own research in accordance with NT BUILD 492 were used.
Keywords: chloride diffusion coefficient; forecasting the durability of HC-500.
