FIELD: hydraulic compositions.
SUBSTANCE: invention relates to an additive for a hydraulic composition. Hydraulic composition additive for use in a hydraulic composition containing a hydraulic binder, wherein the additive comprises dialkanolamine and diethylene glycol, where the dialkanolamine is diethanolamine and/or diisopropanolamine, and where the weight ratio of said dialkanolamine to said diethylene glycol (dialkanolamine/diethylene glycol) is in the range of 0 ,2 to 100.
EFFECT: increasing the initial strength during aging of the material of the cured mass.
