The effect of ultra-fine admixture on the rheological

May 01, 2000· However, ultra-fine AG can significantly increase the viscosity of cement paste. When the UA quantity added is more than 15%, the values of the viscosity (and also the yield stress) of cement paste are significantly decreased with the increase of the UA quantity added and especially, the effect of ultra-fine slag is the most significant.

Effects Of Debranning And Ultra-ifne Grinding On The

Debranning had positive effects on gluten, color,pasting and rheological properties of whole wheat flour. After ultra-fine grinding of wholekernels, the mean particle diameter of whole bule wheat flours distributed from21.33μm to20.22μm with the increase of debranning level. The values of whole purple wheat flour werefrom21.32μm to24.77μm.

Effects of debranning and ultra-fine grinding on the

The effects of debranning levels of 4 and 8% and ultra-fine grinding on physico-chemical, rheological, and pasting properties of wheat flour obtained from blue wheat, as well as cook quality, were investigated. The process of debranning decreased ash (from1.89 to 1.62%) and wet gluten content (from 44.68 to 38.81%), but increased the gluten index of wheat flours (from 12.95 to 17.82).
