Abstract

The hydraulic performance and migration parameters of cementitious mixtures are currently under investigation by an experimental study. The main aim of the research is to investigate the diffusion coefficient and sorption capacity of the mixtures and their interaction with inorganic sulphate solutions at different concentrations, as a function of their composition and curing time. The paper shows and discusses the results related to the hydraulic performance and the sorption capacity as a function of the mixtures composition. Simulations of solute migration through cut-offs made by the different mixtures investigated show the importance of taking into account their sorption capacity to optimize the design.
