摘要：
The invention proposes an adjuvant system for a concrete comprising as a combination:(a) a superplasticizer(b) an accelerator; and(c) a rheology extender.A method for preparing prefabricated concrete is also proposed, comprising the step of adding in a suitable amount, respectively: (a) a superplasticizer; (b) an accelerator and (c) a rheology extender, simultaneously or successively to the concrete slurry. Finally the use of such a system for preparing prefabricated concretes is proposed.
