Method for producing carbonate mineral composition, carbonate mineral composition and method for producing binder composition
The invention relates to a method for producing a carbonate mineral composition, in particular for use as a cement substitute in hydraulic binder compositions, in which a (CaO + MgO)/SiO2 weight ratio is in the range of 1.2 to 5.0:-grinding to obtain a powder; -mixing the powder with water; -putting the paste consisting of mineral components and water into a reactor having a gaseous atmosphere containing CO2; -carbonating the paste in the reactor for a predetermined time; drying the material obtained after hardening to a constant weight; or-grinding the mineral component to a Brinell fineness of from 3,000 cm < 2 >/g to 10,000 cm < 2 >/g to obtain a powder; -injecting a CO2-rich gas into the grinding machine while grinding in the grinding machine, carbonating the components; mixing the powder with water in a solid-to-water weight ratio of between 0.3 and 1.5 to obtain a paste, or by pre-wetting with water in a solid-to-water weight ratio of between 0.03 and 0.2; drying the material obtained after hardening at a temperature of 60-85 DEG C, preferably at a temperature of 80 DEG C, until the weight thereof is constant; -the resulting material is deagglomerated and sieved.
本发明涉及一种制备碳酸矿物成分的方法，该碳酸矿物成分特别是在水硬性粘结剂组合物中用作水泥替代物，其中(CaO+MgO)/SiO2重量比为1.2至5.0的矿物成分：‑经研磨以获得粉末；‑将粉末与水混合；‑将由矿物成分和水组成的糊状物放入具有含CO2的气体环境的反应器中；‑使糊状物在反应器中以预定时间进行碳酸化；‑将硬化后所得的材料干燥至重量恒定；或‑将矿物成分研磨至布莱恩细度为3'000cm2/g至10'000cm2/g，以获得粉末；‑在研磨机中研磨时，向研磨机中注入富含CO2的气体，使成分碳酸化；‑将粉末与水混合，固水重量比在0.3至1.5之间，得到糊状物，或通过加水预湿，固水重量比在0.03至0.2之间；‑将硬化后所得的材料在60‑85℃的温度下干燥，优选在80℃的温度下干燥，直到其重量恒定；‑将得到的材料进行解聚并筛分。
