Structure Formation in Cement Brick Using High-Voltage Corona Discharge for Hydraulic Cement Components
Abstract
The paper presents physicochemical investigations of the structure formation in cement brick provided by high-voltage corona discharge treatment of binder components of hydraulic cements. The effect from the high-voltage corona discharge applied to clinker minerals is evaluated by the X-ray phase, thermal, spectral, and electron-microscopic analyses. It is found that the effect from the high-voltage corona discharge applied to alite modifies the crystallization process, morphology, and the amount of new formations in the hardening system. The effect of dispersion phase of high concentrations is studied in relation to the structure of the corona field and its parameters.
