Abstract
A method for inerting clays in a hydraulic composition includes one step of putting a hydraulic composition or a constituent of a hydraulic composition in contact with a compound of the formula (I) R—COO31, (Mn+)1/n, wherein a method for making hydraulic composition, a pretreated granulate which may be obtained by mixing a granulate with the compound of formula (I), and an additive for inerting clays including a superplasticizer and the compound of formula (I) are described.
