Low-cement periclase concrete with mechanical activation matrix component
Experimental studies unveiling influence of mechanical activation of sintered periclase and mixes «periclase - calcium-alumina cement» on the change of the mineralogical composition of hydrated materials, microstructure and early streak low-cement periclase concrete have been conducted. X-ray diffraction and thermogravimetric analysis, scanning electron microscopy of mechanical activation materials and periclase concrete have been analyzed. Effect of lock of hydrated periclase after joint treatment mixes «periclase - calcium-alumina cement» in a vibrating mill was established. Properties of low-cement periclase concrete in distance of temperatures 20-1650 °С have been defined. As a result of carried out tests low-cement periclase concrete in the drum blowing lance of molten metal manganese the positive results were received.
