摘要
A process for producing a binder (cement) to be used in slurry, mortar, or concrete having a low water-to-cement ratio. As raw-material for the binder is used at least 50% by weight of a hydraulic material, such as slag, technical pozzolanas and/or natural pozzolanas. The hydraulic material is ground to a specific surface of at least 400 m2/kg. To the raw-material is added 0.1 to 5% by weight of a plasticizing material, such as a sulphonated polyelectrolyte. To the raw-material are also added in total 0.5 to 8% by weight of sodium carbonate and/or sodium hydroxide. Added in small amounts, the sodium carbonate and the sodium hydroxide, separately or in combination, considerably shorten the hardening time of the concrete, yield excellent strengths, and make it possible to use cheap raw-materials.
