Abstract
In this study, the leaching of inorganic and organic species from micro fine cement suspensions for grouting purpose was investigated. The leaching experiments were conducted according to the German tank leaching test with demineralised water and Berlin tap water and lasted up to 56 days. The release behaviour of the superplasticiser was studied by total organic carbon (TOC) measurements and ultraviolet-visible spectroscopy (UV-Vis) detection. Depending on the availability and the solubility of the inorganic species, the release is controlled by the water to cement (w/c) ratio and porosity thereafter. The eluent is also responsible for the leached amount of ions, whereas Berlin tap water is less aggressive. Even adsorption of ions is possible when leaching with Berlin tap water. Superplasticiser leaching is controlled by surface wash-off effects during the first leaching steps, followed by diffusion. UV-Vis measurements showed that only up to 2 % of the total active component of the superplasticiser can be released. As the superplasticiser is a mixture of melamine and naphthalene sulfonate condensate, their release happens in a two-stage process. During the first leaching steps, melamine sulfonate condensate is leached, which alternates later on to a favoured leaching of naphthalene sulfonate condensate.
