Use Of Marble As Limestone In Cement

  • Understanding Limestone in Cement| Concrete

    The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation

  • Commercial Limestone and Marble Explained

    Commercial marble is more compact than commercial limestone, and it takes a good polish. In commercial use, these definitions aren't limited to rocks made of calcite; dolomite rock is just as good. In fact, serpentinite too has minerals softer than granite and is considered a commercial marble under the names serpentine marble, green marble or verd antique.
