Investigating Synthetic Dolomite Mixtures and Phase Adjustment Parameters in Electrochemical Cement Precursor Production [PDF]

Chemphyschem
The electrochemical dissolution of synthetic dolomite mixtures and reconstitution into hydroxide precursor phases suitable for Portland cement and Mg‐based cements is investigated. Adjustments of the experimental parameters during electrolysis allow for adjustments in product phase distribution, shedding insight into mixture separation techniques in ...
