The effect of calcium lignosulfonate on ettringite formation in cement paste

Atomic Si/Ca, Al/Ca and Cl/Ca-ratios of the C-S-H in the HCl-samples with 0 and 22 mL acid added. The results from the present study are compared to those from Sui et al. The

limestone replacement by mass leads to higher sedimentation rate and takes less time to reach the plateau than the reference cement paste wc0.5wp0.5, while the coarser

In addition to increase the efficiency of the mill, some grinding aids also provide important positive effects on the final cement such as, rheology of the fresh cement paste or
