wollastonite from waste ash

  • Research: Aggregate Uses Canadian Wollastonite

    Dec 19, 2013 Abstract: Engineering characteristics of concrete mixes incorporating marble slurry dust (marble waste), wollastonite micro fibres (natural mineral), flyash and silica fume were studied in the laboratory. Workability of the concrete mixes was found to diminish as the proportion of Marble Slurry Dust (MSD)
