Preparation method of low-carbon spheroidized marine silicate and cement prepared from low-carbon spheroidized marine silicate
The invention provides a preparation method of low-carbon spheroidized maritime work silicate and cement prepared from the low-carbon spheroidized maritime work silicate. The low-carbon spheroidized maritime work silicate cement has the particle size and interval accumulative distribution as follows: 13%-23% of a part with the particle size smaller than 3 microns, 50%-70% of a part with the particle size smaller than 32 microns and 8%-18% of residues on a square hole sieve with the particle size smaller than 45 microns. The invention also provides a preparation method of the low-carbon spheroidized maritime work Portland cement. The mixed material is directly fed into a novel dry-process energy-saving vertical grinder for grinding and shaping. The particle size distribution of the low-carbon spheroidized cement is optimized, the circularity is improved, the length-diameter ratio is reduced, the distribution interval of the length-diameter ratio and the circularity of particles is small, the particle size distribution is more reasonable, the particle stacking density is improved, and the particle morphology is obviously improved, so that the cement standard consistency water consumption is reduced, the mortar fluidity is improved, and the hydration heat is lower; the early strength is proper, the later strength is higher, the inherent quality of the cement is improved, and low energy consumption is realized.
本发明提供一种低碳球形化海工硅酸盐的制备方法及其水泥，所述低碳球形化海工硅酸盐水泥的粒径及区间累计分布为：＜3μm占比13‑23％，＜32μm占比50‑70％，45μm方孔筛筛余8‑18％；还提供一种低碳球形化海工硅酸盐水泥的制备方法，所述混合材料直接喂入新型干法节能型立式研磨机进行研磨整形。本发明通过对低碳球形化水泥粒径分布进行优化，提高圆形度，降低长径比，且颗粒长径比和圆形度分布区间小，粒径分布更加合理，提高颗粒堆积密度，明显改善颗粒形貌，使得水泥标准稠度用水量降低，胶砂流动度提高，水化热更低，早期强度适当，后期强度更高，提升水泥内在品质，并实现低能耗的制备方法。
