Abstract (en)
[origin: WO2022248442A1] The present application concerns the use of a molecule producing an aqueous solution exhibiting a dispersive portion of more than 25%, for improving workability retention in a hydraulic composition based on a hydraulic binder composition comprising at least one hydraulic binder comprising aluminosilicates and a maximum of 10% by weight of clinker, preferably from 0 to 10% by weight of clinker.
