Wet carbonization method for producing auxiliary cementing material
A method of making an auxiliary cementitious material is described, the method comprising: forming a slurry comprising water and a carbonizable material powder, where the weight ratio of water to the carbonizable material powder is at least 1; and flowing a gas comprising carbon dioxide into the slurry for 0.5 to 24 hours while maintaining the slurry at a temperature of 1 DEG C to 99 DEG C to form a carbonated slurry comprising CaCO3 and amorphous silica. A method of forming cement or concrete using the auxiliary cementitious material is also described.
本发明描述了一种制备辅助胶凝材料的方法，该方法包括：形成包含水和可碳化材料粉末的浆料，其中水与所述可碳化材料粉末的重量比为至少1；以及使包含二氧化碳的气体流入浆料中0.5至24小时，同时将浆料保持在1℃至99℃的温度下，以形成包含CaCO3和无定形二氧化硅的碳酸化浆料。本方法还描述了一种使用所述辅助胶凝材料形成水泥或混凝土的方法。
