Abstract:
The present invention is mainly aimed at a set-accelerating admixture for hydraulic compositions comprising, in an aqueous solution, the reaction product of an alkanolamine with a concentrated strong acid; sulfate anions; and alkali or alkaline earth cations; having a pH comprised between 5 and 12. Moreover it is directed to a method for its preparation as well as to a method for preparing hydraulic compositions comprising the step for adding such an admixture to the hydraulic binder, before, during or after the grinding.
