Abstract: The invention relates to the use of an additive composition in the form of an aqueous solution or dispersion having a solids content in the region of 5 to 75% in wt. with respect to the total weight of the additive composition, obtained according to a method consisting of mixing the components a) and b) in an aqueous medium, wherein a) is selected from sodium zirconium carbonate, potassium zirconium carbonate, ammonium zirconium carbonate and mixtures thereof, b) is selected from at least one ortho-phosphate, at least one condensed phosphate, salts thereof and mixtures as additives in starch glue.

Abstract: The invention relates to suspensions, to the production of said suspensions, and to the use thereof for accelerating the setting and hardening of cement and mixtures containing the same. According to the invention, said suspensions consist of aluminium sulphate in a quantity of more than 8 wt. % as Al2O3, preferably between 10 and 12 wt. %, and of suspended bentonite in a quantity of between 1 and 7 wt. %. Said suspensions can especially be used as economical and ecological alternatives in the field of wet spraying. The inventive suspensions are free of COD and alkali.
