Abstract
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 including aluminosilicates and a maximum of 10% by weight of clinker preferably from 0 to 10% by weight of clinker.

A method for improving the workability retention of 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, comprising the addition of at least one molecule whose aqueous solution of said molecule presents a dispersive portion of more than 25%, to said hydraulic composition.
A hydraulic composition comprising a hydraulic binder composition comprising at least one hydraulic binder comprising aluminosilicates and a maximum of 10% by weight of clinker, an activator of blast furnace slag and/or other aluminosiliceous sources, water, an aggregate and optionally one or more mineral additions, and at least one molecule producing a mixing water having a dispersive portion of more than 25%.
