Zusammenfassung:The invention provides low-carbon spheroidized cement and a preparation method thereof. The particle size and interval accumulative distribution of the low-carbon spheroidized cement are as follows: the proportion less than 3 microns is less than or equal to 14%, the proportion less than 32 microns is less than or equal to 75%, the proportion less than 45 microns is less than or equal to 88%, and the proportion less than 80 microns is less than or equal to 98%. The circularity is 0.75 to 0.90, and the length-diameter ratio is 1.25 to 1.60; and the residue on a 45-micron sieve is 7-30%. 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, the distribution is closer to Fuller curve distribution, and the particle morphology is o
