Dissolution of powdered quartz

Nature, 1975
POWDERED quartz exhibits an initially high solubility rate but opinions are divided as to the cause. Clelland1 argued in favour of the ‘Beilby layer’—a skin of vitreous material produced during grinding; whereas Talbot2 stated that the numerous small particles which were always found adhering to the larger particles of quartz offered a plausible ...

The Structure of Powdered Quartz

Nature, 1973
DIFFERENTIAL thermal analysis (d.t.a.) of quartz normally reveals an endothermic peak at 573° C, corresponding to the inversion from low quartz to high quartz. If the quartz is subjected to grinding it is observed that the peak size decreases, both in height and area; this effect is usually attributed to conversion during grinding of quartz to some ...

Effects of Quartz Powder on the Microstructure and Key Properties of Cement Paste

open access: yesSustainability, 2018
This paper compares the effects of the water-to-binder (w/b) ratio and quartz contents on the properties of cement–quartz paste. The w/b ratios of the paste mixtures specimens are 0.5 and 0.2, and the quartz powder contents are 0, 10, and 20%.
