Chloride diffusivity in high strength concrete at different ages

The chloride diffusivity in high strength concrete blended with and without silica fume was determined at different ages by using a rapid method recently developed by the authors of this paper. The quantitative relations between diffusivity and curing age were obtained and expressed by a regression equation. The chloride penetration was evaluated and discussed by applying Fick's law taking diffusivity as the age dependent variable. For the covering abstract see IRRD 851601.
