    摘要： There is described a thixotroping and set accelerating additive for mixtures which contain as component a hydraulic binder and/or a latent-hydraulic binder and furthermore water and optionally also an aggregate and/or other additives. The inventive thixotroping and set accelerating additive consists of one or more esters of the carbonic acid or said additive is a mixture which has a pH-value of not more than 8.0, preferably not more than 7.5 and contains as component at least one of said carbonic acid esters.Optionally the inventive additives can comprise further components which frequently are added to materials containing a hydraulic binder in order to improve the workability and/or the properties of the final building material, like concrete plasticizers, concrete super-plasticizers, set retarding agents, set accelerating agents, air entraining agents and optionally further thixotroping agents and mixtures of two or more such additives. The present invention furthermore concerns a mixture containing a hydraulic binder and the inventive additive and furthermore a process for preparing such a mixture and an apparatus for performing the process.
