Abstract
The method of vibration ball milling is applied in this paper to make research on contents of lignosulfonate and modified composites as cementgrinding aids; and studied on the influence of regularity about grinding aids on products fluidity, particle size, specific surface area and powder particle size distribution. The study showed lignosulfonatehas had better effect on the cement grinding function; the cement’s particle size and the distribution were improved, the average diameter was decreased, distribution narrowed and ultra-fine grain size increased, of the most importance, the contents of ultra-fine grain size were increased much. Among those, the effect of calcium lignosulfonate was relatively good while its modified composites performed better.
