Investigations on the leaching behaviour of irrigated construction elements.
OBJECTIVE
In this paper, results regarding the leaching of trace elements out of mineral building materials under irrigation are presented.


RESULTS
The leaching in the irrigation test is compared with the leaching under constant water exposure to determine the relevance of the irrigation scenario for the assessment of the environmental compatibility of mineral building materials.
