Overview
This document describes a method for determining the release behavior during curing of grouts that cure in contact with soil and groundwater. These construction products contain organic and inorganic substances that can be emitted into soil and groundwater, among other things by leaching. In principle, the method described in this document is suitable for producing injection agent test specimens and obtaining eluates from the percolation or flow around these specimens during the curing of the injection agents. The eluates are prepared in such a way that inorganic and organic substances can be determined in them and their effect on biological systems (ecotoxicological tests) can be investigated. The short- and long-term elution behavior is recorded by the time sequence of the eluate fraction extraction. This document has been prepared in Subcommittee NA 119-01-02-05 UA "Elutionsverfahren" ("Leaching methods") of NA 119-01-02 AA "Abfall- und Bodenuntersuchung" ("Waste and soil investigation") of the DIN Standards Committee Water Practice (NAW).
