    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.

    摘要： Additives are disclosed which inhibit the corrosion of metals in construction materials which contain an inorganic binder. The inventive corrosion inhibitors contain a reaction product of amines and acids or they consist of such a reaction product. Said saltlike corrosion inhibitors upon use do not develop any undesired fragrance, and they furthermore do not bring along any health risks for the persons who are working with said substances. Through the adding of the inventive corrosion inhibitors, furthermore the properties of the construction material during its preparation and also during its use can be improved. In corresponding processes for inhibiting the corrosion of metals which are in contact with the construction materials, like e.g. metal armings, the corrosion inhibitors are usually added in an amount of 0.01% by weight to 10% by weight of said reaction product, referred to the inorganic binder which is contained in such material. Construction materials which contain the inventive corrosion inhibitors provide a corrosion inhibition of any metal parts embedded into said construction materials over decades of years.
